Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

Browse source 
Pull kbuild changes from Michal Marek:
 - LTO fixes, but the kallsyms part had to be reverted
 - Pass -Werror=implicit-int and -Werror=strict-prototypes to the
   compiler by default
 - snprintf fix in modpost
 - remove GREP_OPTIONS from the environment to be immune against exotic
   grep option settings

* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  kallsyms: Revert back to 128 max symbol length
  Kbuild: Ignore GREP_OPTIONS env variable
  scripts: kallsyms: Use %zu to print 'size_t'
  scripts/bloat-o-meter: use .startswith rather than fragile slicing
  scripts/bloat-o-meter: ignore changes in the size of linux_banner
  kbuild: replace unbounded sprintf call in modpost
  kbuild, bloat-o-meter: fix static detection
  Kbuild: Handle longer symbols in kallsyms.c
  kbuild: Increase kallsyms max symbol length
  Makefile: enable -Werror=implicit-int and -Werror=strict-prototypes by default
