kumquat-buildroot/package/mysql_client/mysql_client-5.1.53-configure-ps-cache-check.patch

Patch borrowed from
http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/mysql/files/configure-ps-cache-check.patch

It allows to specify through ac_cv_FIND_PROC how ps should be used on
the target to find the PID of a program.
