[Buildroot] [PATCH 1/3] glibc: ensure BR2_MAKE is also used for subdirs

[Peter Korsgaard <peter@korsgaard.com>]

The configure script contains logic to figure out what make program to
invoke for subdirectories (trying gnumake, gmake, make).  Explicitly force
it to use our BR2_MAKE to ensure the right make version is used.
