+These tests were imported from 'glibc/elf' and are responsible for testing
+the TLS functionality of the dynamic loader. The file 'tls-macros-mips.h'
+is a copy of 'glibc/sysdeps/mips/tls-macros.h'. Dependency and link orders
+are critical and should NOT be changed. Even if you think you know what
+you are doing, do not touch the Makefile without posting to the uClibc
+development mailing list.
