I have not attempted to build powerpc-eabi but I may need to do that.
Something is also failing with mips64orion-rtems that I need to look into.

Anyway, I put the gcc command line in a script and then monkeyed with the
arguments.  It looks like -mlittle is enough by itself to break it.  It
breaks with all the arguments, just -mlittle, but works will the args
minus -mlittle.   See this output from my test script:

The only things which vary are the arguments:

In (1), -mlittle -mrelocatable-lib -mno-eabi
In (2), -mlittle
In (3), -mrelocatable-lib -mno-eabi

(1) and (2) report the error.

Any ideas on what to look at?
