[Buildroot] external toolchain : lot's of package broken *.mk makefile

[Matthieu CASTET]

Hi,

I am very interrested to use the external toolchain features, because we want to
use glibc.

The problem with lot's of pakage *.mk makefile is that they assume that the
external libs will be installed in the toolchain dir not another dir.

For example for the procps pakage, there is an error [1].
The solution is to add somethings like
CPPFLAGS=-I$(STAGING_DIR)/include CFLAGS=-I$(STAGING_DIR)/include
LDFLAGS="-L$(STAGING_DIR)/lib -L$(STAGING_DIR)/usr/lib" 

when calling the build process.

Matthieu
