+Subject: [PATCH] ffi_powerpc.h: fix build failure with powerpc7
+
+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
