The problem is with building glibc headers. The specific error is:
No rule to make target m_signbitl.c

I can't find reference to a similar error online anywhere, so I figure 
it's something MinGW specific causing the problem.

Looking further back, both m_signbitl.c and m_signbitl.d were created 
previous to this point, but m_signbitl.c got erased by that final 
'rm'. Could the problem be something with the msys/mingw version of 
make?

There's no telling what sorts of new problems I'll encounter after I
get past this point, but it *is* possible to build a cross-gcc under
mingw/msys for other targets so with a bit of work I hope to get this
target built.

I appreciate any help getting this to work.

Thanks,
Eric
