[meta-freescale] [PATCH][fsl-community-bsp-base] setup-environment: conditionally show MACHINEs

[Trevor Woerner]

Before trying to show the supported MACHINEs, make sure they can be found,
otherwise the error message to "ls" will be displayed (which users might find
confusing).

Tested on: bash, dash, zsh.
