[Buildroot] [PATCH v2 1/3] package/make: add host variant

[Romain Naour <romain.naour@gmail.com>]

Add host variant for make package since glibc 2.28 now require
GNU Make >= 4.0 [1].

We have to ceate gnumake and gmake symlinks to GNU make generated by
Buildroot for the host. Otherwise the one provided by the host system
can be used instead.

For example, the glibc build system is looking for gnumake and gmake
before make. See [2].
