Summary:                    [patch] Host CPP used rather than toolchain CPP
Description: 
Hi All,

Hope all is going well.

buildroot/packages/Makefile.in defines $(TARGET_CONFIGURE_OPTS) to be:

TARGET_CONFIGURE_OPTS=PATH=$(TARGET_PATH) \
                AR=$(TARGET_CROSS)ar \
                AS=$(TARGET_CROSS)as \
                LD=$(TARGET_CROSS)ld \
                NM=$(TARGET_CROSS)nm \
                CC=$(TARGET_CROSS)gcc \
                GCC=$(TARGET_CROSS)gcc \
                CXX=$(TARGET_CROSS)g++ \
                RANLIB=$(TARGET_CROSS)ranlib \
                OBJCOPY=$(TARGET_CROSS)objcopy

but doesn't set CPP. This results in the host CPP be used rather than the
toolchain version and various configure scripts break when this happens,
thinking that a certain header exists in the staging filesystem when they
don't (eg. strace, coreutils, and others).

The attached patch fixes this.

Cheers,

Marcus

that doesnt really make much sense ... configure scripts default CPP to
doing `$(CC) -E` which we override

fixed in svn anyways as it shouldnt break anything
