PROGRAM_DESCRIPTION="\
This program is used to deploy mclinker (ld.mcld) to GCC directories.
Although ld.mcld depends on lots of LLVM modules and is built in
build-llvm.sh to reduce long LLVM compilation time, it can be used as
a drop-in replacement for ld.bfd and ld.gold in GCC.
Running after completion of both build-llvm.sh and build-[host-]gcc.sh,
this script copy toolchains/llvm-$DEFAULT_LLVM_VERSION/prebuilt/$SYSTEM/bin/ld.mcld[.exe]
to be sibling of ld in all GCC and LLVM directories with same HOST_OS and bitness,
ie. {linux, darwin, windows} x {64, 32}
If --systems isn't specified, this script discovers all ld.mcld[.exe] in
toolchains/llvm-$DEFAULT_LLVM_VERSION
Note that one copy of ld.mcld serves all GCC {4.9, 4.8, 4.7, 4.6, 4.4.3} x {arm, x86, mips} and
LLVM {3.4, 3.5}.
GCC passes -m flag for ld.mcld to figure out the right target.
