kbuild: fix "Argument list too long" error for "make headers_check",
I'm trying to install kernel headers to build a cross-toolchain, but got
the following:
make ARCH=arm
INSTALL_HDR_PATH=/work/psl/eldk-builds/arm-2009-04-21/work/var/tmp/crosstool-0.43-3-root/usr/crosstool/gcc-4.2.2-glibc-20070515T2025-eldk/
+arm-linux-gnueabi/arm-linux-gnueabi/
headers_check

make: *** [headers_check] Error 2
->
Introduce use of xargs to fix this.
