Stabs support is missing some types on Solaris/Sparc

[jfv]

On SPARC/Solaris, there are problems with the debug types conversion into the eresi types.

For instance, when librevm is loaded in the shell (which include libasm.a), we have
many asm_ types (including asm_operand) but we dont have asm_instruction. We need
this to be fixed so that we can acheive reflection on assembly instruction, thus allowing
binary code transformation directly from the ERESI language.

It seems like this bug only affects Solaris, further testing must determine it
