Subject: [PATCH] build: remove typo and don't bother with /usr/include/pcre

Problem reported by Holger Bruenjes.
* m4/pcre.m4: Remove test for /usr/include/libpng (a typo).
Come to think of it, don't bother worrying about
/usr/include/pcre, as hosts with that problem can use pkg-config
or configure with CFLAGS by hand.
