[[[ Follow up to r22832. Post r22832 svn build fails if apr, apu, serf all bundled in the subversion src dir. The cause is bundled apr/apr-util is identified as ./apr/apr-config and ./apr-util/apu-config for other consumers like serf. This causes serf's configure to fail.(serf's configure is done from the directory $SVN_SRC_DIR/serf.) The fix is to make apr_config and apu_config as absolute path. * build/ac-macros/find_apr.m4 (APR_FIND_APR): For bundled apr set apr_config to be absolute path. * build/ac-macros/find_apu.m4 (APR_FIND_APU): For bundled apr set apu_config to be absolute path.
