[uclibc-ng-devel] [RFC PATCH v3 0/1] libpthread: Fix inclusion of unwind code.

Okay, I finally managed to get the makefiles right. This patch will include only the code in unwind-forcedunwind, originally used by libpthread. Since the effects are pretty much the same, that works just right. This is even more harmless given the fact that none of the current libc/librt code requires exception handling as in glibc (i.e. no call to any unwinder's function is generated by GCC). As this could change in the future, it's good to have an implementation that will work already there. Apart from the fact that the actual implementation of _Unwind_Resume for ARM was not working properly, the symbols for this and other unwinder's functions was overriding the ones in libgcc_s. The code in glibc doesn't explicitly set the hidden attribute on all these functions, but it eventually uses a version script which makes all these locals. Here, I explicitly set these functions to be hidden, thus avoiding the need to use a version script.
