app-emulation/modules: fix -mpreferred-stack-boundary error

The smpcall.c unit fails to build leading to the failure described in https://bugs.gentoo.org/show_bug.cgi?id=559798#c63 compilation fails when SSE related user flags are set in CFLAGS. This is same condition as described in bug report https://bugs.gentoo.org/show_bug.cgi?id=492964#c9 In the kernel SSE code is generally disabled so -mpreferred-stack-boundary=3 is forced on even on 64 bit systems. If any user CFLAGS requires SSE instructions than the requirement for gcc becomes -mpreferred-stack-boundary=4 leading to a compilation failure. Temporary fix until this is embedded in linux-mod.eclass because it's not specific to vmware, I have opened the bug report #571800.
