As mentioned in https://github.com/projectacrn/acrn-documentation/pull/38
on some operating systems, the ``gnu-efi`` package installs the
linker under a ``gnuefi`` folder in ``${LIBDIR}``. This is the
case in Fedora for example. Check if the gnuefi folder is there
and use it if it is in the path to the linker. This PR fixes the
Makefile rather than documenting how to edit it yourself.

this patch save native lapic configuration and restore it to vm0's vlapic
before its running, then doing hpet timer interrupt injection through vlapic
interface -- this will not mess up vlapic and we can see hpet
timer interrupt coming continuously.

we added uefi stub for hv, and want vm0 continue running under uefi env to
boot other uefi payload (osloader or bzImage).
during this, the uefi timer irq need be handled elegantly.
there are 3 types for uefi timer:
1. 8254 based on IRQ0 of PIC
2. HPET based on IOAPIC
3. HPET based on MSI
currently, we only support type 3 (HPET+MSI). But we are following a
in-correct flow to handle this timer interrupt:
- we set VMX_ENTRY_INT_INFO_FIELD directly if a timer interrupt happened
before vcpu launching, this will make its vlapic mess up, which finally
cause hpet timer stop.
this patch remove this in-correct approach, the new approach patch will
be followed by next patch.

acrn.efi is an EFI executable image and not a linux kernel image.
This commit changes linux to efi in the boot-loader configuration.

The EFI configuration example file is not installed.
This patch adds a rule to install the configuration example file
at /usr/share/acrn

Currently the acrn EFI hypervisor file is installing directly to
/usr/share. This patch adds a "acrn" directory to store in
/usr/share/acrn
