[PATCH] Fix ppc64-linux --with-cpu=default32 build

[Jakub Jelinek]

Hi!

Recent t-linux64 changes broke ppc64-linux --with-cpu=default32.
If -m32 is the default, it doesn't appear on the command line and so
%{!m32:-mlong-double-128} expands to -mlong-double-128 for both 32-bit
and 64-bit libgcc (which means ICEs when trying to expand TImode
shifts in 32-bit mode).
Bootstrapped on ppc64-linux and ppc64-linux --with-cpu=default32.
Ok for trunk/3.4?

	* config/rs6000/t-linux64 (bispecs): Don't add -mlong-double-128 for
	32-bit builds when defaulting to 32-bit.
