I cannot explain why PLT is needed when a libpython function calls a
libpython function.
Because an exported symbol in an ELF shared library is subject to
potential interposition using LD_PRELOAD so the calls need to go
through the PLT to be resolved.
Not sure what PLT is (pre load table?), but is it something what could
be disabled?
This sounds like the whole system could be 25% faster if we link statically.
If we build things statically with libraries, it's a can full of worms.
What needs to be said about this change that we don't staticaly link against
different libraries, we just build CPython source into one "fat" executable
instead of splitting it into a tiny wrapper and a "fat" libpython.
