Ack.  I don't ever recall seeing patches to port the various
subprojects in gdb (bfd, libiberty, gdb itself, etc.), except
gdbserver, which always runs on the target, to
Android/bionic though.
You're likely to hit problems that would need porting work.

 It is coincidence that the error just occurs in the

gdbserver should build for Android.  So the cross scenario we know works.

Right, so the build is failing while building libiberty (primarily a
host abstraction library).  I'm afraid it looks like someone needs to
step up and do some porting work.  Looks like you found an itch to
scratch.  ;-)
