In your case something like this should work:

ffmpeg -i videoaudio -i audio -map 0 -map 1 -codec copy output

btw mpg container have limit for audio tracks (AFAIR 16) - not directly your problem but perhaps someone may have similar issue in future.

Or ImagoMPEG-Muxer.

Or tmpgenc 2.5x http://www.tmpgenc.net/en/download.html - not many people knows that it is equipped with nice and unrestricted mpg muxer (license limitations apply only to MPEG-2 encoding, MPEG-1 and muxing are free, also it has very nice interactive sequence editor that allow to manually mark and modify parameters of every frame in sequence (type, quantization etc).

Yep, in the old tmpgenc under file->mpeg tools can you find the multiplexers and demultiplexers. Also cutting and merging.
