Damien Miller 29cf521486 wrap some autoconf macros in AC_CACHE_CHECK ...

This allows skipping/overriding the OSSH_CHECK_CFLAG_COMPILE and
OSSH_CHECK_CFLAG_LINK macros used to discover supported compiler
or linker flags. E.g.

  $ ./configure ossh_cv_cflag__fzero_call_used_regs_used=no
  [...]
  checking if cc supports compile flag -ftrapv and linking succeeds... yes
  checking if cc supports compile flag -fzero-call-used-regs=used and linking succeeds... (cached) no
  checking if cc supports compile flag -ftrivial-auto-var-init=zero... yes
