MDEV-31727: pcre stack size not functioning on clang-16

noinline attribute was being ignored by clang-16 and reporting
32 stack size on Gentoo, 16 locally on Fedora 38.

Based on https://stackoverflow.com/questions/54481855/clang-ignoring-attribute-noinline
appended noopt in addition to the gcc recognised attributes.

After that the -pcre_exec(NULL, NULL, NULL, -999, -999, 0, NULL, 0)
returned 1056, simlar to gcc.

From https://bugs.gentoo.org/910188.

Thanks Zhixu Liu for the great bug report.
