Hi didn't found the problem,
If look at build log
https://buildd.debian.org/status/fetch.php?pkg=libapr-memcache&arch=mips&ver=0.7.0-1&stamp=1334370101
There is no problem for mips build if look to build server.
I build libapr-memcache as you can see in the rules file :
%:
dh $@
So to ./configure command is done by dh_au
In case of amd64 system it configures like this:
"./configure" \
"--build=x86_64-linux-gnu" \
"--prefix=/usr" \
"--includedir=${prefix}/include" \
"--mandir=${prefix}/share/man" \
"--infodir=${prefix}/share/info" \
"--sysconfdir=/etc" \
"--localstatedir=/var" \
"--libdir=${prefix}/lib/x86_64-linux-gnu" \
"--libexecdir=${prefix}/lib/x86_64-linux-gnu" \
"--disable-maintainer-mode" \
"--disable-dependency-tracking" \
"$@"
In case of mips system it configures like this :
#! /bin/sh
#
# Created by configure
"./configure" \
"--build=mips-linux-gnu" \
"--prefix=/usr" \
"--includedir=${prefix}/include" \
"--mandir=${prefix}/share/man" \
"--infodir=${prefix}/share/info" \
"--sysconfdir=/etc" \
"--localstatedir=/var" \
"--libexecdir=${prefix}/lib/libapr-memcache" \
"--disable-maintainer-mode" \
"--disable-dependency-tracking" \
"$@"
So if you still thinks this wrong for debian as multi arch system then you need
to file bug against debhelper.
Becouse the dh_auto_configure add's the configure options like libexecdir and
libdir if he think it is needed so this is not libapr-memcache bug so I will
mark it as wontfix
Wontfix #722789
