X-Git-Tag: v3.4.0~18
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6f10f125778c87a494509f5612fc43869791d469;p=thirdparty%2Frsync.git

When not using the builtin zlib, link it before linking libcrypto, as libcrypto depends on zlib.

This prevents "undefined symbol" errors which might arise from libcrypto.a if linking openssl statically.
