We only wrap gcc/cc indeed. Packages should not call "ld" directly, as
it breaks a bunch of other situations. For example, on mips64, using
"ld" directly doesn't work as it needs to be passed the "machine
emulation", which gcc does.

So I don't think we need to wrap "ld", as ld shouldn't be used
directly. The only packages that should use "ld" directly are things
like the Linux kernel or bootloaders.

Best regards,

Thomas
