Subject: [PATCH v4 0/3] x86: stack alignment for boot code and clang

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 macro __cc-option and
refactors the macros cc-option and hostcc-option to make use of
__cc-option.

Matthias Kaehlcke (3):
  kbuild: Add __cc-option macro
  x86/build: Use __cc-option for boot code compiler options
  x86/build: Specify stack alignment for clang
