Compiler options where not properly propagated when -localWorkers > 1.

When -localWorkers > 1 the compiler launches server process through
the CompilePermsServer entry point to compile permutations in parallel.

CompilePermsServer would not retrieve the compiler options correctly
since commit a4416918797a13036bbd04e90da077117cfd2c71.
