[Buildroot] [PATCH v2 1/5] Makefile: don't depend on the umask

[Guido Martínez]

Some packages and BR itself create files and directories on the target
with cp/mkdir/etc which depend on the umask at the time of building.

To fix this, change the Makefile's $(SHELL) to always call a wrapper
script first that sets the umask to a sane fixed value (022) and then
calls the real shell.
