Wow :) I didn't expect it to work. :)

But the rest of what I said I know for sure. Look:
I touch libm/w_sqrt.c and run make:

  CC libm/w_sqrt.o
  STRIP -x -R .note -R .comment lib/libm.a
  AR cr lib/libm.a

I touch libm/w_sqrt.c and run make V=1:

gcc -c libm/w_sqrt.c -o libm/w_sqrt.o -include ./include/libc-symbols.h -Wall ...
install -d lib/
rm -f lib/libm.a
strip -x -R .note -R .comment libm/e_acos.o libm/e_acosh.o libm/e_asin.o ... libm/llrintf.o
ar cr lib/libm.a libm/e_acos.o libm/e_acosh.o libm/e_asin.o ... libm/llrintf.o

See? strip is run on .o files, not .a file.
"STRIP -x -R .note -R .comment lib/libm.a" line is lying.
