This may be necessary.

When gccxml builds its builtin GCC parser gets configured as a compiler
targeting the host platform. Look at
to see how each target treats __float128. Note that x86_64 targets will
use the i386.c source (ia64 is for Itanium). That source contains the
condition "if (TARGET_64BIT)" around its support for __float128.
