Installation and Building

Some time ago, we received a report[1], that opencascade won't build against the `musl` libc implementation on Gentoo Linux. Because occt already supports various platforms with their respective libc implementations, I was wondering, if there will be support for lesser used libc implementations on linux as well?

I guess the most straight-forward way would be adding missing `execinfo.h` header to musl library, which is though not yet completely portable, but already available across most platforms.

In the Haiku port that I am currently doing, I am using libexecinfo as a replacement.

For linking it, I used the CSF_psapi variable, which is "close enough", but maybe a new CSF variable should be introduced for this. There are commented out includes for other platforms in Standard_StackTrace.cxx ...
