Fix emulators/qemu40 build with lld 10.0.0

As reported in bug 244251, with clang and lld 10.0.0 the emulators/qemu40 port fails in the configure stage:

===>  Configuring for qemu40-4.0.1

ERROR: We need to link the QEMU user mode binaries at a
       specific text address. Unfortunately your linker
       doesn't support either the -Ttext-segment option or
       printing the default linker script with --verbose.
       If you don't want the user mode binaries, pass the
       --disable-user option to configure.

===>  Script "configure" failed unexpectedly.
Please report the problem to bofh@FreeBSD.org [maintainer] and attach the
"/wrkdirs/usr/ports/emulators/qemu40/work/qemu-4.0.1/config.log" including
the output of the failure of your make command. Also, it might be a good idea
to provide an overview of all packages installed on your system (e.g. a
/usr/local/sbin/pkg-static info -g -Ea).
*** Error code 1

This is because lld 10.0.0 no longer supports the -Ttext-segment option, and uses --image-base for similar functionality.

I am proposing a patch that makes the configure script check for the --image-base option first, then the -Ttext-segment option.
