I think for RTEMS having these libraries built with GCC (statically linked or not) has advantages. The reasons statically linking can be considered harmful are well known [1] how-ever having these libraries that are an important part of the compiler controlled as part of the compiler's configuration set goes a long way to simplifying the verification and validation audit. If I was currently responsible for building a critical application I would like to be able to audit and provide to the V&V team the exact configuration used for testing, development and release. For me this means aways building the tools from source.
