  I've successfully configured, built, and installed gmp 5.0.5 but with one
  problem. I've found that whatever I set PREFIX to, the configure did not
  override that setting when I passed specific options such as --includedir
  or --datarootdir even though they are listed when configure --help is run.
  Here is the specific command I ran "./configure --prefix=/mnt/linux
  --includedir=/mnt/linux/usr/include --datarootdir=/mnt/linux/usr/share
  CFLAGS="-O2 -pipe -march=native" yet everything, including the include and
  share directories were installed in /mnt/linux whereas in all other
  packages I've built so far they were placed in /mnt/linux/usr as I defined
  there. I'll also be including config.log as is suggested on the bug
  reporting page. Thank you for any action taken. I'm not too knowledgeable
  about the Autotools configure system but I can try to take a look at it
  myself and submit a patch if nobody is able to work with this.
  
Thanks for the offer!  We would indeed appreciate help with this.
