Subject: fix-ltdl: Delete libobj symlink before attempting to create it.
X-Git-Url: http://git.draconx.ca/gitweb/dxcommon.git/commitdiff_plain/3b9bc71b625c5f96302b035fdea8fd09171d1cfa

fix-ltdl: Delete libobj symlink before attempting to create it.

There seems to be a (rare) race in parallel builds where make for some
reason decides to update the libobj symlink after it already exists,
which fails.  I can't reproduce the failure, but deleting the symlink
(if one exists) before creating it should avoid the issue.
