[PATCH] Introduce new gold plugin option "relocation-pic"

[Alexey Volkov]

Hi Rafael,

Before clang parses -Wl options there is some logic based on PIE, e.g. crt
object name selection.
One possible solution is to move -Wl options before crt objects.
But I am not sure if such reordering of linker arguments is possible.
Another solution is to parse -Wl option value directly before it is passed
to CmdArgs.
Do you have any other ideas?
