The basic usage is as follows:

- If a spell works with the latest version of gcc, do nothing.
- To change the compiler version for a spell, add a GCC_VERSION field
to the spells DETAILS specifying major.minor version of gcc it needs,
e.g. GCC_VERSION=3.4
- add a 'depends gccXX' to the spell where XX == majorminor,
e.g. 'depends gcc34'
- add 'invoke_gcc' to the top of PRE_BUILD if the spell has a
custom PRE_BUILD file
