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.

+ help
+ Where possible, use static libraries.
+ This increases your code size a lot and should only be
+ used with a good reason why not use the default, which
+ is dynamic libraries.
+
+ If unsure, say No.

+ WARNING: This is highly experimental at the moment.
