I can not make gdbserver

[daiyi]

Hi.
I have a problem about "making gdbserver."
I downloaded the latest edition of gdb --gdb-5.3.tar.gz.But when I followed
steps of the "README" file ,it didn't work.
That is when I put in such word"./configure --target=powerpc-linux" in the
gdbserver directory,linux answer me like this"bash: ./configure: bad
interpreter: Permission denied"
I don't know why?
Can u help me ?
