build: allow building crossgcc when .config exists

Under some circumstances the coreboot toolchain test prevented
    building crossgcc, which is counter-productive: If a .config file
    exists but no suitable .xcompile.

Don't assume anything about the tree when building crossgcc or
    crosstools targets.
