Certain platforms need paging enabled during cache-as-ram because
dirty lines are being evicted by a heavy speculative frontend. Paging
needs to be enabled in order to utilize the NX (no execute) bit for
the regions that are strictly data (such as the stack). This utility
creates 32-bit PAE page tables using a static address space, and
the resulting tables have entries for all the PDPTEs such that it makes
it easy to enable 2MiB naturally aligned DRAM mappings once memory is
trained. Either binary files can be generated or C files. The pages that
are linked use a default base address of 0xaa000000 that can be changed at
runtime to reflect where the page tables are actually loaded. Or
specify a physical address on the command line that is known a priori.

As the code was moved from the Makefile.inc to a separate file in
commit 9ab8ae6a (util/gitconfig: Make gitconfig a bash script),`$(MAKE)`
was replaced by `remake`, introducing dependency on this tool which is
basically a `make` with debugging capabilities. Many developers don't
have `remake` installed, leading to pre-commit hooks being not executed
properly. Apparently this was an unintentional change.
Furthermore, special treatment of `make` tool via the `%MAKE%`
substitution performed during hooks' deployment is still desired. Use
case is calling `remake gitconfig` to set `remake` as the `make` tool in
the hooks. To accomplish this, add a parameter that is passed from the
Makefile.inc to gitconfig.sh.

only a generic hint because the `please_install()` function fails to
detect the OS kind. Detection is based on definition of `ID_LIKE` in
`/etc/os-release` yet such systems only define `ID` to `debian`.
This commit closes the detection gap. Tested on debian 9 (stretch).

They both have a device id of 0x3c. The former is part of the PCI chip set
accessible via port 0x3f0 while the latter is a standalone LPC chip accessible
via 0x2e/0x4e depending on strapping.
They're not register compatible: the VT82C686 only provides a FDC, LPT and part
of UARTs.
The VT82C686 documentation suggests it has revision 0x00 while the VT1211
datasheet indicates 0x01. Nevertheless, the VT1211 I happen to have hs a
revision of 0x02. Thus the revision is probably not good enough to tell one
from the another.
