[Buildroot] [PATCH] /etc/profile: read in /etc/profile.d/*.sh files

[Thomas De Schampheleire <patrickdepinguin+buildroot@gmail.com>]

For custom projects, it is more maintainable to add custom profile settings in a
separate file, than directly in /etc/profile.

This patch modifies /etc/profile to read in *.sh files from /etc/profile.d/, a
technique commonly used in Linux distributions.
