The most relevant difference between frv-uclinux and frv-linux-gnu is
(potentially) in GCC: the former assumes uClibc is the system library,
whereas the latter assumes (or rather could assume) glibc is.
Currently, not even for GCC does it make any difference IIRC.

But since the sys-root will be difference, and uClibc and glibc are
not binary-compatible, you'll likely run into problems, unless you
refrain from using any data structure or function from the C library.
