This depends on the settings. But of course, whatever the method used,
this should be done in the right way (setting ABI=32 and CFLAGS="" is
non-sense if the default ABI is 64-bit). A good example is when the
user installs software under his home directory (~/bin, ~/lib, etc.),
and wants to use them by default, the best solution is to use
environment variables like LIBRARY_PATH and CPATH instead of providing
-L and -I options at each invocation; another advantage is that the
search path order will always be the same, while it is too easy to
swap two options like -L (in case this has an importance).
