Make simulator compile on MacOS

Tested on MacOS Sequoia (Apple Silicon) with the
latest Xcode command line tools, gcc 14
(Homebrew GCC 14.2.0_1) and sdl2 (Homebrew 2.30.9)

Make sure 'gcc' (and 'gcc-ar') is in your PATH
ahead of the Xcode-provided "gcc"(clang). E.g.
by setting up symlinks in /usr/local/bin that
point to gcc-14 and gcc-ar-14.

Notes:
- The appropriate bmp from uisimulator/bitmaps
  has to be manually copied to your build folder
  and renamed to UI256.bmp, if you want the sim
  background to be displayed
