- 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.

+ If unsure, say No.
