IBM Z: Detect libc's float_t behavior on cross compiles
When cross-compiling GCC with target libc headers available and
configure option --enable-s390-excess-float-precision has been omitted,
identify whether they clamp float_t to double or respect
__FLT_EVAL_METHOD__ via a compile test that coerces the build-system
compiler to use the target headers. Then derive the setting from that.
gcc/ChangeLog:
2020-12-16 Marius Hillenbrand <mhillen@linux.ibm.com>
* configure.ac: Change --enable-s390-excess-float-precision
default behavior for cross compiles with target headers.
* configure: Regenerate.
* doc/install.texi: Adjust documentation.
