Subject: build: avoid dlopen-related link failure on rawhide/F13
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=fd04fbaaaf8deb4a7f94622c2c0bde506e36d62c;p=libvirt.git

build: avoid dlopen-related link failure on rawhide/F13

Instead of using AC_CHECK_LIB and hardcoding -ldl, search for the library
needed to get dlopen() and then use the cached value.
