To start with, mips-linux-elf is not supported by gdbserver either with 
out-of-the-box 5.0:

$ ../../configure --target=mips-linux-elf --host=mips-linux-elf
*** ./configure.in has no "per-host:" line.
*** Hmm, looks like this directory has been autoconfiscated.
*** Running the local configure script.
loading cache config.cache
checking host system type... mips-linux-elf
checking target system type... mips-linux-elf
checking build system type... mips-linux-elf
checking for a BSD compatible install... (cached) /usr/bin/install -c
configure: error: *** GDB remote does not support host mips-linux-elf

Can you tell me which sources do you use?

Happy to hear that  you got working GDB. I hope to make one too. For 
this I need to know where to get the MIPS port and your patches.
Can you send them to me?

These are indeed good news.
