This series fixes an issue with the stack of the x86 boot code not being aligned as intended. Further it adapts the Makefile to account for the fact that clang uses a different option to configure the stack alignment than gcc (-mstack-alignment=N vs -mpreferred-stack-boundary=N)
Collaterally the series adds the new kbuild macros cc-option-raw and hostcc-option, it also reworks cc-option to make use of cc-option-raw.
