# OVERVIEW
#
# GNU Linker Veneer
#
# DESCRIPTION
#
# This script wraps normal linker commands that're transparently
# passed-through. It adds ephemeral logging and directory creation.
#
# EXAMPLE
#
# build/linker ld -o program program.o
if [ ! -d o/third_party/gcc ]; then
third_party/gcc/unbundle.sh
fi
export LC_ALL=C # very important for ld
