The make variables LIB_CFLAGS, DSO_CFLAGS and so on were used in
addition to CFLAGS and so on.  This works without problem on Unix and
Windows, where options with different purposes (such as -D and -I) can
appear anywhere on the command line and get accumulated as they come.
This is not necessarely so on VMS.  For example, macros must all be
collected and given through one /DEFINE, and the same goes for
inclusion directories (/INCLUDE).

So, to harmonize all platforms, we repurpose make variables starting
with LIB_, DSO_ and BIN_ to be all encompassing variables that
collects the corresponding values from CFLAGS, CPPFLAGS, DEFINES,
INCLUDES and so on together with possible config target values
specific for libraries DSOs and programs, and use them instead of the
general ones everywhere.

This will, for example, allow VMS to use the exact same generators for
generated files that go through cpp as all other platforms, something
that has been impossible to do safely before now.

C preprocessor flags get separated from C flags, which has the
advantage that we don't get loads of macro definitions and inclusion
directory specs when linking shared libraries, DSOs and programs.

This is a step to add support for "make variables" when configuring.

The check should reject kernel versions < 4.1.0, not <= 4.1.0.

The issue was spotted on OpenSUSE 42.1 Leap, since its linux/version.h
header advertises 4.1.0.

The eventfd syscall is deprecated and is not available on aarch64, causing
build to fail:

    engines/e_afalg.c: In function 'eventfd':
    engines/e_afalg.c:108:20: error: '__NR_eventfd' undeclared (first use in this function)
         return syscall(__NR_eventfd, n);
                        ^

Instead, switch to the newer eventfd2 syscall, which is supposed to be
supported by all architectures.

This kind of issues would be avoided by simply using the eventfd(2)
wrapper from the libc, but there must be subtle reasons not to...

Tested on a aarch64 system running OpenSUSE Leap 42.1 (gcc118 from
https://cfarm.tetaneutral.net/machines/list/ ) and also cross-compiling
for aarch64 with LEDE (kernel 4.9).

This properly fixes #1685.

The test ENGINE effectively used a predictable PRNG because it supplied
a bogus implementation of SHA256 which the old version of OpenSSL's PRNG
used. The new DRBG does not use SHA256 so it is no longer predictable
if the SHA256 implementation is replaced. Use an explicit predictable
PRNG instead.

The assembler already knows the actual path to the generated file and,
in other perlasm architectures, is left to manage debug symbols itself.
Notably, in OpenSSL 1.1.x's new build system, which allows a separate
build directory, converting .pl to .s as the scripts currently do result
in the wrong paths.

This also avoids inconsistencies from some of the files using $0 and
some passing in the filename.

engines/e_padlock.c assumes that for all x86 and x86_64 platforms, the
lower level routines will be present.  However, that's not always
true, for example for solaris-x86-cc, and that leads to build errors.

The better solution is to have configure detect if the lower level
padlock routines are being built, and define the macro PADLOCK_ASM if
they are, and use that macro in our C code.
