pkg-mgr-commands.tex: econf matches configure --help output better

Following the previous change for --disable-static (commit e0aa80c),
check for proper end of string for all option names beginning with
"with", "disable" or "enable". This will mainly affect --with-sysroot,
where false positives have been observed.
