64e3cf3d4f gdb: fix building with system readline 
Building gdb with --enable-targets=all and --with-system-readline hits a
failure in a few targets all related to the inclusion of some opcodes
headers.  The usage of the bundled readline results in an -I to the top
srcdir, but if that isn't used, then there is no such -I path.  A few gdb
targets use this implicitly to include opcodes/ source header files.  So
make sure there is always an explicit -I path to the opcodes/ directory.

11409fac6b sim: always enable support for the --endian option 
The gdb code always passes down -E <little|big> to the sim core when using
the sim target.  But the sim core only recognizes this option when the sim
supports big endian systems.  So for little endian simulators, any attempt
to use the sim target fails with:

(gdb) target sim
gdbsim: invalid option -- 'E'
unable to create simulator instance

Since always respecting the option doesn't cause any problems, do just
that.  If someone tries to use an invalid endian, they'll get an error
anyways.
