export PATH=/tools/local/bin:/tools/local.m68k-elf/bin:$PATH
<path-to-rtems>/configure --target=m68k-rtems
should automatically do what you want.

Furthermore: Using a m68k-elf-gcc won't work with RTEMS.

This should be irrelevant. Any arbitrary cc is supposed to work here.

It will probably not work out of the box. m68k-rtems-gcc is not
identical to m68k-elf-gcc.
