Subject: configure.ac: Use LIBS rather than LDFLAGS to add -ldl to dladdr check
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a2e1dc0cce3f5c4b94123a5fd4de42ecc988ab14;p=mesa.git

configure.ac: Use LIBS rather than LDFLAGS to add -ldl to dladdr check

ec8ebff "Check for dladdr()" erroneously uses LDFLAGS rather than LIBS to add
-ldl to the dladdr check.

Replace the workaround in 39a4cc4 of explicitly checking in libdl, with a more
correct approach of using LIBS.
