gcc-cross-initial: Reinstate limits.h generation fix

The removal of gcc-cross-intermediate inadvertently reintroduced a
problem with the limits.h file being incorrectly/inconsistently
generated.

This reintroduces the protected sysroot ensuring the limits.h file is
always correctly generated. To reproduce the bug, build gcc-cross, then
rebuild gcc-cross-initial and it will reference the limits.h file from
gcc-cross in the sysroot.
