Many (especially ARM) tool chains seem to come with broken or otherwise unusable (for the purposes of builing U-Boot) run-time support libraries `libgcc.a'. By using the "USE_PRIVATE_LIBGCC" setting we allow to use alternative libraries instead.
"USE_PRIVATE_LIBGCC" can either be set as an environment variable in the shell, or as a command line argument when running "make", i. e. $ make USE_PRIVATE_LIBGCC=yes or $ USE_PRIVATE_LIBGCC=yes $ export USE_PRIVATE_LIBGCC $ make
The value of "USE_PRIVATE_LIBGCC" is the name of the directory which contains the alternative run-time support library `libgcc.a'. The special value "yes" selects the directory $(OBJTREE)/lib_$(ARCH) .
Note that not all architectures provide an alternative `libgcc.a' in their lib_$(ARCH) directories - so far, only ARM does.
