The target linker is searched in tools directories (-B) and PATH. First
with target prefix, afterwards without. sysroot is only about searching
for include files as far as the compiler is concerned (and possibly some
special object files / libraries). No idea about gcc-toolchain, it is
not relevant for the systems I care about.
