autoconf: Add fix for sh verses bash issues
Libtool scripts were finding bash was /bin/sh and then using bashisms which then got into sstate and used on machines where /bin/sh might be dash. This changes things to search for bash first since its preferred. We then hardcode bash into the scripts which is more correct. This does mean we have a dependency on bash but many of our scripts have that anyway. (From OE-Core rev: 367a19aaf31bcf997f10d045e7954cc800189052) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

This value is used to determine CONFIG_SHELL and SHELL which may get exported into
|
||||||
|
scripts shared via sstate onto other systems.
|
||||||
|
|
||||||
|
Some systems have /bin/sh -> dash and others /bin/sh -> bash. Bash is preferred
|
||||||
|
but sometimes we can sometimes end up exporting /bin/sh yet use bashisms.
|
||||||
|
|
||||||
|
This patch puts bash first in the search results which avoids the bash/dash confusion.
