It is possible to keep this compatible with both Qt4 and Qt5, but it is
questionable if it is worth the efforts; it would require us to test
this on both of them, and prevent us from using new features in Qt5.
Qt5 was released in 2012, and now widely available.
Drop the Qt4 support.

Meelis Roos reported a {menu,n}config regression:
"I have libncurses devel package installed in the default system
location (as do 99%+ on actual developers probably) and in this
case, pkg-config is useless. pkg-config is needed only when
libraries and headers are installed in non-default locations but
it is bad to require installation of pkg-config on all the machines
where make menuconfig would be possibly run."
For {menu,n}config, do not use pkg-config if it is not installed.
For {g,x}config, keep checking pkg-config since we really rely on it
for finding the installation paths of the required packages.
Fixes: 4ab3b80159 ("kconfig: check for pkg-config on make {menu,n,g,x}config")

Currently, the necessary package checks for building qconf is
surrounded by ifeq ($(MAKECMDGOALS),xconfig) ... endif.
Then, Make will restart when .tmp_qtcheck is generated.
To simplify the Makefile, move the scripting to a separate file,
and use filechk. The shell script is executed everytime xconfig
is run, but it is not a costly script.
In the old code, 'pkg-config --exists' only checked Qt5Core / QtCore,
but the set of necessary packages should be checked.
