+Subject: [PATCH] Fix cross-compilation
+
+Using AC_RUN_IFELSE() in configure.ac breaks cross-compilation:
+
+    configure: error: cannot run test program while cross compiling
+
+Commit 978c7b2e89aa37a7ddfe2f6b6ba12ce73dd04528 caused AC_RUN_IFELSE()
+to be used instead of AC_LINK_IFELSE() because the latter had seemingly
+been causing the check for --wrap support in the linker to not work as
+expected.  However, it later turned out that the problem lied elsewhere:
+a minus sign ('-') was missing from the LDFLAGS variable used in the
+relevant check [1].
+
+Revert to using AC_LINK_IFELSE() for checking whether the linker
+supports the --wrap option in order to make cross-compilation possible
+again.
+
+Fixes: https://gitlab.isc.org/isc-projects/bind9/-/issues/2237
