I talked about this on IRC but simply put, no way.

The problem is:

a) Arm specific
b) determined now to be armv7 specific
c) gcc version specific

and the fix should reflect this.

So ideally when we select gcc 4.6 in tcmode-default.inc we should add
something there which adds a work around for mesa-xlib.

I've suggested something like:

TARGET_CC_ARCH_arm_pn-mesa-xlib := "${@'${TARGET_CC_ARCH}'.replace('armv7','armv5')}"

which whilst ugly, should do what we need it to.

Cheers,

Richard
