Support defining strtof64, strtof32x, wcstof64, wcstof32x aliases.
This patch adds support for defining strtof64, strtof32x, wcstof64, wcstof32x and the corresponding _l functions as aliases of the corresponding double functions when _Float64 and _Float32x support is enabled. Tested for x86_64; also tested with build-many-glibcs.py in conjunction with other _Float64 / _Float32x changes. * stdlib/strtod.c: Include <bits/floatn.h>. (BUILD_DOUBLE): New macro. [BUILD_DOUBLE && __HAVE_FLOAT64 && !__HAVE_DISTINCT_FLOAT64] (strtof64): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [BUILD_DOUBLE && __HAVE_FLOAT64 && !__HAVE_DISTINCT_FLOAT64] (wcstof64): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. [BUILD_DOUBLE && __HAVE_FLOAT32X && !__HAVE_DISTINCT_FLOAT32X] (strtof32x): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [BUILD_DOUBLE && __HAVE_FLOAT32X && !__HAVE_DISTINCT_FLOAT32X] (wcstof32x): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * stdlib/strtod_l.c: Include <bits/floatn.h>. (BUILD_DOUBLE): New macro. [BUILD_DOUBLE && __HAVE_FLOAT64 && !__HAVE_DISTINCT_FLOAT64] (strtof64_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [BUILD_DOUBLE && __HAVE_FLOAT64 && !__HAVE_DISTINCT_FLOAT64] (wcstof64_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. [BUILD_DOUBLE && __HAVE_FLOAT32X && !__HAVE_DISTINCT_FLOAT32X] (strtof32x_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [BUILD_DOUBLE && __HAVE_FLOAT32X && !__HAVE_DISTINCT_FLOAT32X] (wcstof32x_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR].
