remove obstack support

Remove __UCLIBC_HAS_OBSTACK__ as it isn't very uptodate and
maintained part. It shouldn't be required for any software and
mostly shipped with stuff which use it. (f.e. binutils-gdb)

-/* Summary:
-
-All the apparent functions defined here are macros. The idea
-is that you would use these pre-tested macros to solve a
-very specific set of problems, and they would run fast.
-Caution: no side-effects in arguments please!! They may be
-evaluated MANY times!!
-
-These macros operate a stack of objects.  Each object starts life
-small, and may grow to maturity.  (Consider building a word syllable
-by syllable.)  An object can move while it is growing.  Once it has
-been "finished" it never changes address again.  So the "top of the
-stack" is typically an immature growing object, while the rest of the
-stack is of mature, fixed size and fixed address objects.
-
-These routines grab large chunks of memory, using a function you
-supply, called `obstack_chunk_alloc'.  On occasion, they free chunks,
-by calling `obstack_chunk_free'.  You must define them and declare
-them before using any obstack macros.
-
-Each independent stack is represented by a `struct obstack'.
-Each of the obstack macros expects a pointer to such a structure
-as the first argument.
-
-One motivation for this package is the problem of growing char strings
-in symbol tables.  Unless you are "fascist pig with a read-only mind"
---Gosper's immortal quote from HAKMEM item 154, out of context--you
-would not like to put any arbitrary upper limit on the length of your
-symbols.
-
-In practice this often means you will build many short symbols and a
-few long symbols.  At the time you are reading a symbol you don't know
-how long it is.  One traditional method is to read a symbol into a
-buffer, realloc()ating the buffer every time you try to read a symbol
-that is longer than the buffer.  This is beaut, but you still will
-want to copy the symbol from the buffer to a more permanent
-symbol-table entry say about half the time.
-
-With obstacks, you can work differently.  Use one obstack for all symbol
-names.  As you read a symbol, grow the name in the obstack gradually.
-When the name is complete, finalize it.  Then, if the symbol exists already,
-free the newly read name.
-
-The way we do this is to take a large chunk, allocating memory from
-low addresses.  When you want to build a symbol in the chunk you just
-add chars above the current "high water mark" in the chunk.  When you
-have finished adding chars, because you got to the end of the symbol,
-you know how long the chars are, and you can create a new object.
-Mostly the chars will not burst over the highest address of the chunk,
-because you would typically expect a chunk to be (say) 100 times as
-long as an average object.
-
-In case that isn't clear, when we have enough chars to make up
-the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
-so we just point to it where it lies.  No moving of chars is
-needed and this is the second win: potentially long strings need
-never be explicitly shuffled. Once an object is formed, it does not
-change its address during its lifetime.
-
-When the chars burst over a chunk boundary, we allocate a larger
-chunk, and then copy the partly formed object from the end of the old
-chunk to the beginning of the new larger chunk.  We then carry on
-accreting characters to the end of the object as we normally would.
-
-A special macro is provided to add a single char at a time to a
-growing object.  This allows the use of register variables, which
-break the ordinary 'growth' macro.
-
-Summary:
-	We allocate large chunks.
-	We carve out one object at a time from the current chunk.
-	Once carved, an object never moves.
-	We are free to append data of any size to the currently
-	  growing object.
-	Exactly one object is growing in an obstack at any one time.
-	You can run one obstack per control block.
-	You may have as many control blocks as you dare.
-	Because of the way we do it, you can `unwind' an obstack
-	  back to a previous state. (You may remove objects much
-	  as you would with a stack.)
