dosbox @ 0.74-6 Build fails with XCode 6.1 (with patch)

[NF6X (Mark J. Blair)]

After upgrading to Yosemite and XCode 6.1, dosbox failed to build with the following output:

...emulators/dosbox% sudo port install dosbox
Warning: All compilers are either blacklisted or unavailable; defaulting to first fallback option
--->  Computing dependencies for dosbox
[...]
--->  Configuring dosbox
Warning: All compilers are either blacklisted or unavailable; defaulting to first fallback option
[...repeated many times...]
--->  Building dosbox
Error: org.macports.build for port dosbox returned: command execution failed
Please see the log file for port dosbox for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_emulators_dosbox/dosbox/main.log
[...]
Error: Processing of port dosbox failed

Log file included several instances of errors similar to this one:

:info:build ./core_dyn_x86/../../fpu/fpu_instructions_x86.h:1165:2: error: ambiguous instructions require an explicit suffix (could be 'filds', or 'fildl')

Applying the fpu.diff patch provided in ticket #40789 (attached for convenience) and removing the clang blacklist statement from the Portfile (new patch attached) allowed a clean build.
