toolchain.eclass: fortify hybrid workaround
* Make sure the result is non-empty before trying to use it as an index
* Make sure the result is an integer before trying to use it as an index
* Don't try to set --param ... if we had no result at all
These are good ideas anyway but they happen with gnat-gpl as apparently
older GCC didn't actually have the l1-cache-size thing (I thought it was a bit
older than 10). Whatever.
