[Qemu-devel] [RFC][PATCH] Use HOST_CC instead of CC on TCG only targets

[Aurelien Jarno]

Now that we have 3 TCG only targets (arm, cris, sparc) and 1 being
actively converted (mips), I think it does not make sense anymore to
build those targets with gcc-3.4.

For example on hppa, gcc-3.4 is buggy and unable to compile
target-sparc/softmmu.c. OTOH, I haven't found any noticeable speed
improvement comparing gcc-3.4 and gcc-4.3.

The patch below is maybe a bit hackish, but enables the use of the
default compiler for TCG only targets. I am not sure it is worth doing
a more complex patch given than all targets are supposed to be converted
to TCG sooner or later.
