Recent ARM newlib and libgloss changes

[Richard Earnshaw]

The recent changes to newlib and libgloss seem to have seriously broken
testing of gdb and libjava.

newlib is being built in 'compatibility' mode.  That is, without
--disable-newlib-supplied-syscalls.

The problem seems to be that despite this, gcc is picking up the version
of crt0.o that is built into libgloss, but that version does not contain
the correct code for setting up an RDI execution environment.
