libc/uClibc: add patch to fix fork in threads with ARM EABI

uClibc-0.9.32 requires libgcc_eh.a (for ARM EABI), but only when libubacktrace
is enabled. As this is not the default, provide a workaround to disable linking
with libgcc_eh.a if libubacktrace is not selected.

This will however still break if uClibc is configured to enable libubacktrace,
but it requires a fix in gcc, and we can take care of that later.

     3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,
     4 MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
     5 for e500v2 DPFP support) and will generate appropriate dual-precision
     6 floating point instructions by default.

     8 Note: If building a Linux kernel with this toolchain, you will want to make
     9 sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions
    10 from getting into the kernel (which is currently unsupported). At this time,
    11 the kernel build system properly passes those two options, but older kernels
    12 were only passing -mno-spe by default."
