New description:

 On certain shells, the "-e" option is not supported, and causes echo to
 output the flag along with the quoted text.

 {{{

 -> % sh
 $ echo -e "foo bar"
 -e foo bar
 $
 }}}

 This varies by shell, and is not even consistent between sh or bash.

 It was introduced [https://devel.rtems.org/ticket/3254#comment:78 while
 removing the make preinstall stage here], and may still work on most
 shells, though it didn't for me on sh on Ubuntu 16.04 LTS
 (4.4.0-78-generic x86_64 GNU/Linux) - as far as I can tell, this bug
 hasn't made it to any releases yet, so just fixing it on master should be
 enough.

 A patch is attached.

 Reference to the POSIX standard which confirms that -n is the only
 argument supported.
