For historical reasons MINSIGSTKSZ is a constant which became
already too small with AVX512 support. Add a mechanism to
enforce strict checking of the sigaltstack size against the
real size of the FPU frame. This option enables the check
by default. It can also be controlled via the kernel command
line option 'strict_sas_size' independent of this config
switch. Enabling it might break existing applications which
allocate a too small sigaltstack but 'work' because they
never get a signal delivered.
Say 'N' unless you want to really enforce this check.
