2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------ From: Michael S. Tsirkin <[email protected]> commit 751386507701010831d72c522171753d2cd903d2 upstream. This makes it possible to build perf statically, by performing: make LDFLAGS=-static Since static libraries are only searched in the order they are specified, move library list from LDFLAGS to EXTLIBS, so that they are put at the end of linker command line.
