[Buildroot] Question on UCLIBC_CONFIG_FILE usage.

[Steven J. Hill]

I am obviously missing something here. If I do not specify UCLIBC_CONFIG_FILE
on the command line to make, then a config file in 'toolchain/uClibc' will be
used. None of the values assigned to it in the target directories will ever
be picked up because the top-level Makefile does 'include target/Makefile.in'
last which is too late for 'toolchain/uClibc/uclibc.mk' to pick up the value
in a target-specific directory. Anyone care to comment? Thanks.
