Rollup merge of #83771 - asomers:stack_overflow_freebsd, r=dtolnay

Fix stack overflow detection on FreeBSD 11.1+

Beginning with FreeBSD 10.4 and 11.1, there is one guard page by
default.  And the stack autoresizes, so if Rust allocates its own guard
page, then FreeBSD's will simply move up one page.  The best solution is
to just use the OS's guard page.
Empowering everyone to build reliable and efficient software.
