New Revision: 214696

URL: http://svn.asterisk.org/svn-view/asterisk?view=rev&rev=214696
Log:
Ensure that CFLAGS and/or LDFLAGS provided to configure script are preserved.

Cross-compilation environments want to provide 'defaults' for compiler and
linker options, and frequently do this by specifying CFLAGS and LDFLAGS in the
environment or as command-line arguments to the configure script. This patch
modifies the configure script and Makefile to preserve these settings and
ensure they are used in the build process.
