PR gcc/42525: Avoid tr '\n', for Solaris /usr/bin/tr.

[Ralf Wildenhues <Ralf dot Wildenhues at gmx dot de>]

Bootstrapped and regtested on x86_64-unknown-linux-gnu.
This patch has a couple of typos fixed over the one posted in
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42525#c1>.

OK for trunk?  This should be safe for ASCII hosts, according to the
portability section of the Autoconf manual.

An alternative way to "fix" this PR would be to change this
recommendation in install.texi for *-*-solaris2*:

     The build process works more smoothly with the legacy Sun tools so,
  if you have `/usr/xpg4/bin' in your `PATH', we recommend that you place
  `/usr/bin' before `/usr/xpg4/bin' for the duration of the build.


Thanks,
Ralf
