[PATCH: gdb-7.8-branch] gdbserver: fix uClibc whithout MMU.

[Romain Naour]

Since commit d86d4aafd4fa22fa4cccb83253fb187b03f97f48, the pid
must be retrieved from current_inferior.

The change has not been made in the function linux_read_offsets().

The patch is OK to the mainline, with a ChangeLog entry.  I don't know
we'll have releases on 7.8 branch.

Can you commit your patch to git mainline? or you want me to commit it
for you.

Thanks for your review, I'll send an updated patch rebased on master.

If you are interested, take a look at gdb's build 7.8.2 result:
http://autobuild.buildroot.net/?reason=gdb-7.8.2

gdb 7.9 is not yet tested by autobuilders.

Yes please, I don't have git access to commit my patch.
