libm/Makefile.in: reformat the list of wrappers

 so that it is easier to modify, sort, etc;
 use __ in filenames of wrappers which wrap __functions
 (it may be useful to have function and file names ALWAYS match);
 remove names of not implemented wrappers (it was generating useless
 empty .o files).
libm/ldouble_wrappers.c: comment out the wrapper which is
 not compiled anyway
test/math/compile_test.c: improve this test, it was optimizing out some calls,
 and we don't want that.

No actual code changes.
