clang 10's -Wimplicit-fallthrough does not understand /* FALLTHROUGH */
comments and we don't use the __attribute__((fallthrough)) that it's
looking for. This has the effect of turning off -Wimplicit-fallthrough
where it does not currently help (particularly with -Werror). ok djm@
When using clang with -ftrapv or -sanitize=integer the tests would pass
but linking would fail with "undefined reference to __mulodi4".
Explicitly test for this before enabling -trapv.
platform hardening options: include some long long int arithmatic
to detect missing support functions for -ftrapv in libgcc and
equivalents, actually test linking when -ftrapv is supplied and
set either both -pie/-fPIE or neither. feedback and ok dtucker@
hardening flags including -fstack-protector-strong. These default to on
if the toolchain supports them, but there is a configure-time knob
(--without-hardening) to disable them if necessary. ok djm@
options, we should corresponding -W-option when trying to determine
whether it is accepted. Also includes a warning fix on the program
fragment uses (bad main() return type).

Thanks to tim@ for testing on affected platforms.
