Actually the glitch is happening due to always toggling between slave mode

Since the spi driver only supports master mode, set the mode for all channels
always to master mode in order to have a stable, "glitch-free" SPI clock line.

shell.
This patch fixes this issue by moving the SHELL variable setup and export to the
top config.mk, so that all Makefile-s including it use the same shell.
Since BASH is used by default, this makes it possible to use things
like 'echo -e ...' in sub-makes, which would otherwise fail e.g. with /bin/sh
symlinked to /bin/dash on Ubuntu.
