Introduce qmake feature use_gold_linker
This patch adds the feature use_gold_linker to use the gold linker that
has been part of of GNU binutils since 2008. Gold links C++ libraries
much faster and use less memory.
The feature is autodetected when building Qt on Linux, but can be disabled
in configure. On MingW builds it is default off but can be enabled for
cross builds.
