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.
