$ echo -ne "=CONFIG_FOO\n=CONFIG_Bar\n=CONFIG_bAz\n" | sed 
"s/=\(CONFIG_[[:alnum:]_]\+\)/=$(\1)/"
-bash: 1: command not found
=CONFIG_FOO
=CONFIG_Bar
=CONFIG_bAz
$ uname -a
FreeBSD foo.bar.baz 8.3-RELEASE-p6 FreeBSD 8.3-RELEASE-p6 #9: Tue Feb 26 
17:05:09 CET 2013     foo at bar.baz.foo:/usr/obj/usr/src/sys/XXXXX  amd64
