build.sh has non sh-isms in it

Raghavendra reported:

There are a couple of instances of "echo -n" in scripts/build.sh in the 2011.4.0.0 source installer. The builtin echo command in sh on Mac OS X Lion doesn't accept the `-n' option, e.g., "echo -n foo" just prints "-n foo". In case it hasn't been already done, I suggest that the instances of "echo -n" in build.sh be replaced with "printf", as mentioned in the echo(1) manpage on Mac OS X Lion.

There seems to be a typo in line 137 of build.sh. It looks like "${will_installed}" should be replaced with "${will_install}".
