Replace the use of uname to get the build output.

Browse source 
Using uname has a couple of problems, especially when cross compiling. Instead
check the defines set by the preprocessor to figure the type of binaries it
produces. This improves support for cross compiling as it allows to (1) select
the correct default target and (2) makes it possible to use separate build
folders for different targets.
