    gdb/arm-linux-tdep.c: Handle Thumb2 signal trampolines
    
    Recent versions of glibc have assembled the signal trampoline code
    as Thumb2, which causes gdb to misinterpret them and a number of
    testsuite tests to fail. Educate gdb about these trampolines and
    get the tests running again.
