Disallow gcc versions 4.1.{0,1}
These compiler versions are known to miscompile __weak functions and
thus generate kernels that don't necessarily work correctly. If a weak
function is int he same compilation unit as a caller, gcc may end up
inlining it, and thus binding the weak function too early.
See
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27781
for details.
