Be aware that many packages don't have any build-time testsuites so just because a program is built for a given architecture doesn't gaurantee it actually works.

Re: Raspberry Pi as a coding environment

One issue at the moment is that freepascal doesn't currently support the hardfloat ABI so if you want to use freepascal (which afaict is the dominant pascal compiler for linux) and you want to link pascal code with C code you will have to use a distro that uses the softfloat ABI.
