Using the bit_scripts, I have encountered the following problem:
gmake: Entering directory

Note that files are being included from the host /usr/include
directory. This can't be right.
It is right, though. gdb is built for the host, not the target. You
aren't going to run gdb on your target board, you're going to run it
on your Unix system.
You didn't mention your host, but whatever it is the quick fix would
be to just remove the conflicting declarations of getpagesize from
mmalloc/mvalloc.c and mmalloc/mmap-sup.c.
