Fix m68k bits/math-inline.h macro namespace (bug 22035).
As shown by build bot failures <https://sourceware.org/ml/libc-testresults/2017-q3/msg00349.html> the m68k bits/mathinline.h is not namespace-clean: it fails to compile if the user has defined macros f or l before it is included, because of expansions of those arguments to __inline_functions. This patch changes the __inline_functions definitions to take not the suffix but a macro that concatenates it with the function name, to avoid the spurious macro expansions. Tested for m68k with build-many-glibcs.py. [BZ #22035] * sysdeps/m68k/m680x0/fpu/bits/mathinline.h (__inline_functions): Define to take a second argument that is a macro that concatentates a suffix, not the suffix itself. (__CONCAT_d): New macro. (__CONCAT_f): Likewise. (__CONCAT_l): Likewise.
