libffi: reword the note about "building for another system"
Telling the user to override CFLAGS and CXXFLAGS may cause two problems:
1. We've added --with-gcc-arch=native, so the configure script will add
"-march=native" into CFLAGS. Then we've not really verified which
-march= value is the last one in the GCC command line and being really
used.
2. User may just export CFLAGS="-march=x86_64", without "-O2". This
will produce unoptimized binaries.
