pcre_stack_guard was our addition to pcre to fix stack overflow issues.
we have pcre in the source tree and it was patched to have
pcre_stack_guard. We've also submitted the patch upstream and it got
into pcre-8.34 (iirc). So our CMakeLists.txt tests whether
pcre_stack_guard is present in the system pcre and if not - uses bundled

I suspect that your native system pcre is 8.34 or later and your
cross-compilation pcre is older, so cmake thought that it can use system
pcre and later that failed. You can fix it either by upgrading your
cross-compilation pcre or by forcing bundled pcre.
