perf tools: Allow to specify custom linker command
perf tools: Allow to specify custom linker command

Allow to specify custom linker command. This fixes MIPS64 builds for
64-bit userspace as it will allow to pass a linker using the correct
linker flags for 64-bit ABI (by default GNU binutils ld will assume
N32).
