      kbuild: enable 'make CFLAGS=...' to add additional options to CC · a0f97e06
      Sam Ravnborg 提交于
      The variable CFLAGS is a wellknown variable and the usage by
      kbuild may result in unexpected behaviour.
      On top of that several people over time has asked for a way to
      pass in additional flags to gcc.
      
      This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
      tree and enabling one to use:
      make CFLAGS=...
      to specify additional gcc commandline options.
      
      One usecase is when trying to find gcc bugs but other
      use cases has been requested too.
      
      Patch was tested on following architectures:
      alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k
      
      Test was simple to do a defconfig build, apply the patch and check
      that nothing got rebuild.

      kbuild: fix up CFLAGS usage · 9a39e273
      Sam Ravnborg 提交于
      Only in very rare cases is it needed to change CFLAGS
      outside of arch/*/Makefile.
      Fix up all wrong cases - in most cases
      the use of EXTRA_CFLAGS is the only thing needed.
