This doesn't mean much more but your scripts to be lacking generality.

I vehemently disagree:

* arm-rtems4.11/gcc-4.8 would be eabi.
* arm-rtems/gcc-4.7 would fail to build
* arm-rtems4.11/gcc-4.7 would expect *-eabi
* arm-rtems4.11/gcc-4.6 would be abi.

* arm-rtems* would apply conventions arm*eabi users do not expect.

There is no mess, IMO, this all is bikesheding for no technical reasons 
but for personal reasons.

All this patch would do is to replace a clear separation with a mess and 
cause further mess. Of course you (Chris) will not experience much of 
the mess Sebastian is causing, because you are not packing the toolchains.
