You are hit be an outstanding issue with -rc1 + rc2.
When you build as root you will alter /dev/null and in your case it
became a regular file.
Recreate /dev/null and build as normal user for now.
You can apply patch below to fix it - will be in next -rc.

kconfig: fix /dev/null breakage
While running "make menuconfig" and "make mrproper"
some people experienced that /dev/null suddenly changed
permissions or suddenly became a regular file.
The main reason was that /dev/null was used as output
to gcc in the check-lxdialog.sh script and gcc did
some strange things with the output file; in this
case /dev/null when it errorred out.
Following patch implements a suggestion
from Bryan O'Sullivan <[email protected]> to
use gcc -print-file-name=libxxx.so.
Also the Makefile is adjusted to not resolve value of
HOST_EXTRACFLAGS and HOST_LOADLIBES until they are actually used.
This prevents us from calling gcc when running make *clean/mrproper
Thanks to Eyal Lebedinsky <[email protected]> and
Jean Delvare <[email protected]> for the first error reports.
