The cause for this breakdown is a typo in RTEMS gcc-patch, which had
been reported and fixed looong time ago. Unfortunately it still seems to
be contained in RTEMS current toolchain.


As a work around, check your
/opt/rtems-4.6/lib/gcc-lib/i386-rtems/3.2.3/specs

for the "lib:"-rule and edit -gcc into -lgcc in this line.
