This reverts commit 4fff5ab241.  In
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=45252> we decided to apply a
patch to master instead, so this change is no longer needed on core-updates.

Subject: [PATCH] ffi_powerpc.h: fix build failure with powerpc7
This is a patch pulled down from the following:
https://github.com/buildroot/buildroot/blob/78926f610b1411b03464152472fd430012deb9ac/package/libffi/0004-ffi_powerpc.h-fix-build-failure-with-powerpc7.patch
This issue is being hit on OpenBMC code when pulling the latest
libffi tag and building on a P8 ppc64le machine. I verified this
patch fixes the issue we are seeing.
Below is the original commit message:
Sicne commit 73dd43afc8a447ba98ea02e9aad4c6898dc77fb0, build on powerpc7
fails on:
In file included from ../src/powerpc/ffi.c:33:0:
../src/powerpc/ffi_powerpc.h:61:9: error: '_Float128' is not supported on this target
typedef _Float128 float128;
^~~~~~~~~
Fix this build failure by checking for __HAVE_FLOAT128 before using
_Float128, as _Float128 is enabled only on specific conditions, see
output/host/powerpc64-buildroot-linux-gnu/sysroot/usr/include/bits/floatn.h:
/* Defined to 1 if the current compiler invocation provides a
floating-point type with the IEEE 754 binary128 format, and this glibc
includes corresponding *f128 interfaces for it. */
#if defined _ARCH_PWR8 && defined __LITTLE_ENDIAN__ && (_CALL_ELF == 2) \
&& defined __FLOAT128__ && !defined __NO_LONG_DOUBLE_MATH
# define __HAVE_FLOAT128 1
#else
# define __HAVE_FLOAT128 0
#endif
