kconfig: do not require pkg-config on make {menu,n}config 



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.

The build system, as of 4.18, requires pkg-config to check for installed

kconfig tools and to determine flags settings for use in

'make {menu,n,g,x}config'.  Previously pkg-config was being used but not

'make {g,x}config'.  Previously pkg-config was being used but not

verified or documented.
