Make it more explicit and visible when pkg-config is not found
Users seem to struggle to read the full error message. This adds an
indication if pkg-config is actually found to the warning/error message
that use pkg-config.
On platforms that do not require pkg-config and for optional libraries,
the existence of pkg-config is mentioned as part of the error/warning message.
When found:
configure: error: libnl-genl-3.0 package not found or too old. Is the development package and pkg-config (/usr/bin/pkg-config) installed? Must be version 3.4.0 or newer for DCO
not found:
configure: error: libnl-genl-3.0 package not found or too old. Is the development package and pkg-config (not found) installed? Must be version 3.4.0 or newer for DCO
On platforms where pkg-config is required (only Linux at the moment),
configure will abort when not detecting pkg-config:
checking for pkg-config... no
configure: error: pkg-config is required
