Re: VirtualBox-6.0.6 fails build under 8.99.39

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

The reason for the compilation failure under -current is revision 1.27
of cpufunc.h, which has a bunch of 'asm volatile' statements. The gcc
online documentation states:
...
6.47.1 Basic Asm — Assembler Instructions Without Operands
A basic asm statement has the following syntax:

asm asm-qualifiers ( AssemblerInstructions )
The asm keyword is a GNU extension. When writing code that can be
compiled with -ansi and the various -std options, use __asm__ instead
of asm (see Alternate Keywords).

Qualifiers
volatile
The optional volatile qualifier has no effect. All basic asm blocks
are implicitly volatile.
....

So I replaced every 'asm volatile'   with '__asm__'. Now it compiles
and runs fine.

This probably is not right if one uses clang for OS building, but I am
not there yet.
