# Scope .NOTPARALLEL to the generated locale headers/data only.  A bare
# .NOTPARALLEL: (without prerequisites) used to be specified here, but
# since this Makefile.in is `include`-d into the top-level Makefile, the
# bare form serializes the *entire* uClibc-ng build, defeating make -jN
# across every architecture, every target, since 2016.  The prerequisite
# form (GNU Make 4.4+) limits the serial-only build to the locale data
# generation, which is the original intent.  GNU Make < 4.4 silently
# falls back to global serialization, i.e. previous behavior, so this
# change is forward- and backward-compatible.
