[Gdb] remote gdbserver; main has no line number information

[David Wuertele]

I compiled gdbserver on a mipsel target (--host=mipsel-linux) then
compiled gdb on an intel host (--host=i686-pc-linux-gnu
--target=mipsel-linux).  There seems to be something wrong with the
symbol parsing.  On the target:

# gcc -o hello -g -g3 -ggdb -ggdb3 -static hello.c
# /usr/local/bin/gdbserver 0:8888 ./hello
Process ./hello created; pid = 356

On the dev host:

/usr/local/bin/mipsel-linux-gdb

Single stepping until exit from function main, 
which has no line number information.

Why doesn't main have any line number information?
When I try to create a breakpoint, it complains:

(gdb) sym hello
Reading symbols from hello...done.

Any suggestions?
