lang/fpc-devel: New port: Free Pascal compiler with Turbo and Delphi (devel)

Free Pascal is a mature, versatile, open source Pascal compiler. It can target
many processor architectures: Intel x86 (16 and 32 bit), AMD64/x86-64, PowerPC,
PowerPC64, SPARC, SPARC64, ARM, AArch64, MIPS, Motorola 68k, AVR, and the JVM.

Supported operating systems include Windows (16/32/64 bit, CE, and native NT),
Linux, Mac OS X/iOS/iPhoneSimulator/Darwin, FreeBSD and other BSD flavors, DOS
(16 bit, or 32 bit DPMI), OS/2, AIX, Android, Haiku, Nintendo GBA/DS/Wii,
AmigaOS, MorphOS, AROS, Atari TOS, and various embedded platforms. Additionally,
support for RISC-V (32/64), Xtensa, and Z80 architectures, and for the LLVM
compiler infrastructure is available in the development version. Additionally,
the Free Pascal team maintains a transpiler for pascal to Javascript called
pas2js.
