Subject: configure: fix to make older pkg-config play well
X-Git-Tag: curl-7_24_0~174
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=11e52ef0a157acd6a6711b7635cda50467e606ae;p=thirdparty%2Fcurl.git

configure: fix to make older pkg-config play well

configure.ac:1349: error: possibly undefined macro: PKG_CONFIG_LIBDIR

Obviously this is not a problem with pkg-config 0.26 but older versions
seem to show this.

Fix suggested by: Kamil Dudka
Reported by: Guenter
