BUG: emulators/dosbox fails to build on Intel Mac

[jake.hamby@…]

Since dosbox has some special support for x86 CPUs, it needs to be compiled with the "-mdynamic-no-pic" flag on Intel Macs or else some inline asm will fail to compile. This should also give a (small)performance boost on PPC.

In general, it is beneficial to add "-mdynamic-no-pic" when building performance-sensitive apps on Mac OS X (although you can't use it when building shared libraries), especially on x86, which is register-poor. Here's my Portfile patch for dosbox:
