Bugs: ASTERISK-24502
    https://issues.asterisk.org/jira/browse/ASTERISK-24502


Repository: Asterisk


Description
-------

When coverage and dev-mode are enabled with DONT_OPTIMIZE, it causes build failure.  The double compilation does a 'shadow' build of each file with output to /dev/null.  Unfortunately when coverage is enabled, GCC tries writing to /dev/null.gcno (at least some versions do).  This prevents the build from proceeding.

This change prevents coverage from being enabled for the shadow build of all files.  This involves using a separate variable to hold the CFLAGS for coverage, and adding it to the commands for all real builds.

Testing
-------

Build with these options now works in Linux Mint 17 (gcc 4.8.2-19ubuntu1).


Thanks,
