Date: 2007-06-01 15:16:28 -0700 (Fri, 01 Jun 2007)
New Revision: 18723

Log:
- add BR2_PREFER_STATIC_LIB config option to be able to select if we prefer to build static or dynamic libs/bins.
- depending on the BR2_GNU_BUILD_SUFFIX, set the respective EXEEXT, LIBEXT, SHREXT extensions for use on the target.
Thanks to Tom for suplying a diff which implements these.
