   4 Subject: [PATCH] powerpc: fix build failure on power7 and older (#532)
   5
   6 Build failure looks as:
   7 ```
   8 libtool: compile:  powerpc-unknown-linux-gnu-gcc \
   9     -O2 -mcpu=powerpc -mtune=powerpc -pipe ... -c src/powerpc/ffi.c ...
  10 In file included from src/powerpc/ffi.c:33:
  11 src/powerpc/ffi_powerpc.h:65:9: error: '__int128' is not supported on this target
  12    65 | typedef __int128 float128;
  13       |         ^~~~~~~~
  14 ```
  15
  16 The fix avoids using __int128 in favour of aligned char[16].
