(gdb) py print gdb.parameter("endian")

(gdb) set endian big
The target is assumed to be big endian
(gdb) py print gdb.parameter("endian")
big
(gdb) set endian little
The target is assumed to be little endian
(gdb) py print gdb.parameter("endian")
little
(gdb) set endian auto
The target endianness is set automatically (currently little endian)
(gdb) py print gdb.parameter("endian")
auto
(gdb) show endian
The target endianness is set automatically (currently little endian)

So that's at least one obvious bug ("" vs "auto"), and one more
complex bug (what should it return for auto?).  I'm inclined to say
that it should return auto, and there should be some other way to find
out "auto what?"; OTOH, it's a general problem with parameters...
