Subject: Use sh as the shell for rcm
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

rcm only requires a POSIX-compliant shell – not Bash. The various sh
options in Debian are POSIX-compliant, and many of them are
substantially faster than Bash. Force rcm to run under /bin/sh.

+regardless of what shell’s interpreting the configure script.
