This made it so that python.exp is untested on targets that do
not support shared libraries (e.g., arm-eabi), despite the host
supporting python. I don't suppose you see a problem with
splitting these new tests out into their own files? I've
added a python-1.c file so that python.exp still sees two
files, in case it is important to have more than one symtab.
I've tested this on x86_64-linux, and I was trying to test
python.exp on i686-mingw32 x arm-none-eabi, though it
appears I'll have to give up on that for the moment due to
system issues...
