# Remove LLVM.  I cannot get llvm to build when llvm was present during the building of the
# gcc package.  Removing llvm before building gcc makes llvm build again.

# Ensure the kernel headers package is installed.  These should always be installed
# but it doesn't hurt (unless you're in the middle of building something else)

ORIGPATH=$PWD # store this location because we change to /usr/include below
#( cd /usr/include
#  rm -rf linux asm-arm asm-generic asm
#  removepkg kernel-headers
# Incase I ever forget and delete them from the main ARMedslack tree, I've copied a working Kernel
# headers from Linux 2.4.26.  In the past I have found 2.6 headers break building gcc.
