what happened to musl's intl & gnu's argp:
currently, gnu has fixed this bug.
so this project is to provide another choice than the old argp-standalone.
remove all files, and link the modified version:
truncate -s 0 gnulib/lib/argp*
ln -sf /usr/include/argp.h gnulib/lib/argp.h
LDFLAGS="$LDFLAGS -l:libargp.so.0"
or just overwrite, since argp symbols from gnulib are weak symbols:
CFLAGS="$CFLAGS -l:libargp.so.0"
