I'm not sure what the problem was but I had checked out the code on a windows machine and then copied it over to a linux box. That was causing problems somehow.

I've managed to compile qemu and seabios but vgabios is taking forever to compile. The problem seems to be bcc. I've tried a simple helloworld program and even that seems to be taking forever to compile. Not sure if there is something wrong with my bcc install.

  I'm not sure. configure script isn't modified.
  Can you compile normal qemu?
  The first line of the script is #!/bin/sh. I suppose you have /bin/sh.

  No. Most Linux destro has bcc package. Just you need to install it like
  yum install bcc or something.
