The problem: Say you have gcc-4.2.4 installed and try to build
qemu-old, which needs gcc-3.3.6...

WARNING: "cc" looks like gcc 4.x
Looking for gcc 3.x
gcc 3.x not found!
QEMU is known to have problems when compiled with gcc 4.x
It is recommended that you use gcc 3.x to build QEMU
To use this compiler anyway, configure with --disable-gcc-check
*** Error code 1
<---------------
This tightens the build depends so that only gcc3 (gcc4) will be
accepted where gcc3 (gcc4) is required and not the other version.
Since these are only build depends, no bumps should be required.
