[Buildroot] [PATCH v2 1/1] package/Makefile.in: set --shuffle=none for MAKE1

[James Hilliard]

Make 4.4 introduces a shuffle mode which randomizes prerequisites
in order to better flush out issues with parallel builds, as this
mode randomizes prerequisites even when using -j1 builds we must
also explicitely mark parallel incompatible builds by setting
--shuffle=none which disables goals prerequisites randomization
for the parallel incompatible package when running in shuffle mode.
