-powerpc: fix build failure on power7 and older (#532)
-
-Build failure looks as:
-```
-libtool: compile: powerpc-unknown-linux-gnu-gcc \
- -O2 -mcpu=powerpc -mtune=powerpc -pipe ... -c src/powerpc/ffi.c ...
-In file included from src/powerpc/ffi.c:33:
-src/powerpc/ffi_powerpc.h:65:9: error: '__int128' is not supported on this target
- 65 | typedef __int128 float128;
- | ^~~~~~~~
-```
-
-The fix avoids using __int128 in favour of aligned char[16].
-
-Closes: https://github.com/libffi/libffi/issues/531

-Update powerpc sysv assembly for ffi_powerpc.h changes (#541)
-
-Some of the flag bits were moved when adding powerpc64 vector support.
-
-Fixes #536

-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
-
-Fixes:
