[U-Boot] [PATCH] arm: add __aeabi_unwind_cpp_pr1() function to avoid linker complaints
With the ELDK 5.1 (beta) "armv7a" toolchain I'm get the following build failure:
$ ./MAKEALL mx51evk ... /opt/eldk-5.1/armv7a/sysroots/arm-linux-gnueabi/usr/lib/arm-linux- gnueabi/4.6.1/libgcc.a(bpabi.o):(.ARM.exidx+0x0): undefined reference to `__aeabi_unwind_cpp_pr1' make: *** [u-boot] Error 1
This patch fixes the issue similar to commit d442b6e7ad6a86e2fd0e6297291fe8872ff26fc6 but I don't know if it's general enough or if it does harm when using other toolchains.

Applied to u-boot-arm/master, with a minor tweak: removal of the blank line at end of patch which git was complaining about. Again, hope Wolfgang D will accept a last-day pull request.
Amicalement,
