[Buildroot] [git commit] package/php: fix building pcre extension

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=745f884e41b5f350296e8448f5fc31d20f67a077
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The configure option "--with-pcre-regex=$(STAGING_DIR)/usr" is broken.
PHP will  prepend $(STAGING_DIR)/usr to the paths, which will cause a
failure because it won't be able to find pcre, and will then fallback to
searching for pcre2, which won't be installed.

Removing "=$(STAGING_DIR)/usr" from --with-pcre-regex fixes the issue.
