meta-environment: Two critical fixes to unbreak toolchains

Firstly, when multilib builds were being used, the same output files
were used in each case, being overwritten each time due to the fact that
REAL_MULTIMACH_TARGET_SYS has been expanded. Instead of immediate
expansion, just use assignment. This overrides the problematic define
in toolchain-scripts.bbclass but allows the multilib code to work.

Secondly, the target sysroot was being defined incorrectly which
this patch fixes. This was breaking the toolchains.
