I'm not sure that syscalls in Thumb code are even supported at all, actually.
Your best bet for now is probably to build only the ARM version of libgcc.
Might be worth asking the experts on linux-arm-kernel@lists.arm.linux.org.uk
what the current thinking is on a Thumb system call ABI. If one does exist,
we should fix GCC to use it in this case.
