add note on using ld

[gbowne1]

I'm assuming that the linker ld is just getting confused here but I tried both capitalized flags and lowercase flags.

This is what it reports on my system.

ld -d says "no input files"
ld -g says "no input files"
ld -i says "no input files"
ld -m says "missing argument to m"
ld -n says "no input files"
ld -q says "no input files"
ld -r says "no input files"
ld -s says "no input files"
ld -t says "no input files"
ld -v reports the version
ld -x says "no input files"

ld -E says "no input files"
ld -G says "no input files"
ld -E says "no input files"
ld -M says "no input files"
ld -N says "no input files"
ld -Q says "no input files"
ld -S says "no input files"
ld -U says "no input files"
ld -V is the same as -v but reports the emulations
ld -X says "no input files"
