# Ensure base ARM packages are installed first:

# Ensure $PKGNAM isn't already installed.
# We want to build with gcc since we have a cross toolchain for it.  Building
# llvm with llvm takes >1 day, although this is what we do on x86 Slackware.
# Perhaps in the future.
#
# We need llvm to build itself now, since libcxxabi does not build with gcc.

# Some package builds remove llvm, so let's make sure it's
# present.  There is a bootstrap option to build llvm with GCC but
# we use a self-hosted llvm to build itself in Slackware.

# There's a problem with gcc-go on arm at the moment in that it seems to stall
# when the system is under load, which causes the Go test on LLVM to fail; so
# let's remove it util it works again.
