From: Mark Wielaard Date: Fri, 8 Jan 2016 12:35:33 +0000 (+0100) Subject: Simplify code and build now that zlib support is no longer optional. X-Git-Tag: elfutils-0.165~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=dd131168e2abf2f0fc872829e1101366395cc390;p=thirdparty%2Felfutils.git Simplify code and build now that zlib support is no longer optional. Now that we always require zlib support we don't need to conditionally build or compile code that depends on it.
