Provide an additional macro expansion for F128 in stdlib/tst-strtod.h
The macro F128 in stdlib/tst-strtod.h is defined to provide the literal suffix for _Float128 constants. It uses the macro __f128 (), which is defined in bits/floatn.h to provide the correct literal suffix depending on what is provided by the compiler. However, F128 was not being expanded and only worked correctly, when compiling with GCC 7 (or greater), since F128 is the literal suffix itself. This patch adds an additional macro expansion so that the macro F128 expands to the correct literal suffix on older compilers. * stdlib/tst-strtod.h (MMFUNC): New macro to provide an addition macro expansion. (GEN_TEST_STRTOD_FOREACH): Use MMFUNC for _Float128.
