[Qemu-devel] [PATCH v2] qemu/configure: fix CFLAGS handling for i386

[Olaf Hering <olaf@aepfle.de>]

configure will generate incorrect CFLAGS which will lead to compile
errors due to unknown gcc options, iff CFLAGS was already in the
environment during configure invocation.

Add a space before the -march=i486 gcc option.
Remove += operator usage because configure is not a bash script.

This patch is against the qemu-xen tree, but it should apply also to
qemu.git since it has the same issue. Please apply to both trees.
