Tavis has just reported, that he was recently trying to track down a
reproducible crash in a compressor. Believe it or not, it really was a
bug in zlib-1.2.11 when compressing (not decompressing!) certain inputs.
Tavis has reported it upstream, but it turns out the issue has been
public since 2018, but the patch never made it into a release. As far as
he knows, nobody ever assigned it a CVE.

(cherry picked from commit b3aa2909a7)
(cherry picked from commit 3965dda0fa)
Our pkg-config wrapper relies on the ability to redefine the $prefix and
$exec_prefix variables in order to construct proper search paths relative
to the build environment.
Patch the .pc file template to construct libdir, sharedlibdir and includedir
relative to the ${prefix} variable so that it can be overridden as needed.
This also fixes the libxml2/host build issue raised at
https://github.com/openwrt/packages/issues/6073 - it was caused by libxml2's
configure picking up a wrong host search path through zlib.pc, letting it
include the wrong endian.h, causing spurious member redeclaration errors in
system headers.
