[PATCH 4.4 15/73] kbuild: Do not run modules_install and install in paralel

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michal Marek <mmarek@xxxxxxx>

commit a85a41ed69f27c4c667d8c418df14b4fb220c4ad upstream.

Based on a x86-only patch by Andy Lutomirski <luto@xxxxxxxxxxxxxx>

With modular kernels, 'make install' is going to need the installed
modules at some point to generate the initramfs.
