[Qemu-devel] [PATCH RFC] Makefile.target: prepend $libs_softmmu to $LIBS |

I discovered a problem when trying to build QEMU statically with gcc.
libm is an element of LIBS while libpixman-1 is an element in
libs_softmmu. Libpixman references functions in libm, so the original
ordering makes linking fail.
This fix is to reorder $libs_softmmu and $LIBS to make -lm appear after
-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.
Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.
