This can be fixed by setting your PKG_CONFIG_PATH to the correct 
location of your cross compile pc files.

This is the test to see if ./configure needs to define its own version 
of mktemp so is not a problem in itself. However it is unusual not to 
have it on a system as its part of core-utils.

The same error as the mktemp test, but this time its serious....

It looks like gcc might not even be installed.
