dev-db/mariadb-connector-c-3.0.7 installs /usr/lib/pkgconfig/libmariadb.pc instead of /usr/$(get_libdir)/pkgconfig/libmariadb.pc. (dev-db/mariadb-connector-c-3.0.6-r1 installs this file in correct directory.) Probably caused by: https://github.com/MariaDB/mariadb-connector-c/commit/2a49494c0977205fe1e88e98816a9d6a942688be Solution is to backport https://github.com/MariaDB/mariadb-connector-c/commit/44b21bf642c6eeacbebeeea512078b8d488147cb (already included in 3.0.8 tag which is maybe not yet officially released) and to set -DINSTALL_PCDIR="$(get_libdir)/pkgconfig" in ebuild.

(The patch was renamed, but dev-db/mariadb-connector-c-9999 still references the old patch, and the new patch would actually fail to apply...)
