Subject: build.py: Add a symlink for the logging
X-Git-Tag: 2011-1~4373
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=8e429accb89e098b5bdf4f090ff851a1d2dafbf7;p=openembedded-core.git

build.py: Add a symlink for the logging

[BUGID #375]

When configuring for the log file output, we generate a symlink to the
target filename.  This link uses the same file naming, but without the
active pid, making it easier to see which log file is the last one
generated.
