build.sh is intended for /bin/sh but uses bash-specific syntax $(command)

You need to either change first line to #!/bin/bash or change line 143 to machine=`gcc -dumpmachine 2>/dev/null` which is /bin/sh's way to express $(...)

Seems that Solaris's /bin/sh is really what the name says - the old POSIX shell where on Linux it is a symbolic link to bash
