# FP_CC_LINKER_FLAG_TRY()
# --------------------
# Try a particular linker to see whether we can use it. In particular, determine
# whether we can convince gcc to use it via a -fuse-ld=... flag.
#
# $1 = the name of the linker to try
# $2 = the variable to set with the appropriate GHC flag if the linker is
# found to be usable
