[uClibc][PATCH] Fix 'make defconfig'

[M. R. Brown]

The attached patch fixes the defconfig target.  Note you need a
extra/Configs/Config.$(TARGET_ARCH).default file for defconfig to work, this
just fixes the issue where $(TARGET_ARCH) wasn't being resolved in conf.

The modification to Makefile feels like a kludge, but I couldn't think of a
better way to pass TARGET_ARCH atm.
