[Julien Muchembled]

I don't understand the commit message: we build mariadb with its bundled pcre. But maybe with recent pcre, we can revert d57770ac.

[Kazuhiko Shiozaki]

Indeed, when I committed this change, we already built mariadb with bundled pcre.

Not better with pcre 8.43 and MariaDB 10.4.12:

-- Looking for pcre_stack_guard in pcre
-- Looking for pcre_stack_guard in pcre - found
-- Performing Test PCRE_STACK_SIZE_OK
-- Performing Test PCRE_STACK_SIZE_OK - Failed
CMake Error at cmake/pcre.cmake:22 (MESSAGE):
  system pcre is not found or unusable

But with 2 Debian patches (1 for each of the 2 components), MariaDB builds.

pcre authors won't fix it: they prefer developers to switch to pcre2, and that's actually what MariaDB did in 10.5.
