+Subject: [PATCH] Fix combreloc test with BSD grep
+
+The test for "-z combreloc" fails when cross-compiling on a machine
+that uses BSD grep (e.g. on macos). grep complains about empty
+subexpression and exits with non-zero status, which is interpreted
+by configure as "not found". As a result, support for "-z combreloc"
+(HAVE_Z_COMBRELOC) is not detected, leading to link failure on SPARC.
+
+ * configure.ac: Avoid empty subexpression in grep.
+
