[PATCH] Add powerpc64-linux configuration options

2012-05-23 Thread Michael Meissner
On powerpc64-linux systems that run on IBM servers, the 32-bit software emulation library is not built with the Red Hat and SUSE distributions, but the FSF sources still list it as a multilib. This patch adds a configuration option (--disable-ppc64-swfloat) to disable building this library.
