Don't call setenv in gost2814789t.c

The call to setenv in gost2814789t.c is not portable and may
not reflect the location of the GOST ENGINE on all platforms anyway.
Instead set OPENSSL_ENGINES in test/Makefile

Add conditional unit testing interface.

Don't call internal functions directly call them through
SSL_test_functions(). This also makes unit testing work on
Windows and platforms that don't export internal functions
from shared libraries.

By default unit testing is not enabled: it requires the compile
time option "enable-unit-test".

Emit PERLASM_SCHEME to fix GitMake on OS X

This fixes the errors when trying to assemble .s files using GitMake on OS X.
{,darwin64-}debug-test-64-clang Configure targets

These are based on debug-ben-debug-64-clang and is intended to produce
consistent settings for folks involved in the unit testing effort detailed at:

-fsanitize has been removed from the set of clang flags for now. Apparently
clang 3.1, which ships with FreeBSD 9.1, completely ignores -fsanitize. Clang
3.3, which ships with FreeBSD 9.2, compiles with it, but fails to link due to
the absence of libasan:

We need -Wno-error=unused-const-variable because of this error:

static const char EC_version[] = "EC" OPENSSL_VERSION_PTEXT;
Improve variable parsing when generating MINFO

Before this change, variables for which a '=' appeared in the assignment would
be parsed as the entire string up until the final '='. For example:

  BUILD_CMD=shlib_target=; if [ -n "$(SHARED_LIBS)" ]; then \

would result in the variable name "BUILD_CMD=shlib_target". This doesn't
appear to harm the current generation of MINFO, but creates problems for other
Makefile-related work I'm attempting.
Remove redundant test targets outside of test/

These correspond to targets of the same name in test/Makefile that clash when
using the single-makefile build method using GitConfigure and GitMake.
Ignore dependency makefiles
Add missing SRC variable

This is the only Makefile without SRC defined. This change enables a
standard Makefile include directive to cover crypto/jpake/*.d files.

This was automatically applied by AddSrcVarIfNeeded() in:

Fix CC in FIPS_BUILD_CMD and FIPS_CRYPTO_BUILD_CMD

This should have been $(CC) all along; removing $(BUILDENV) from the
make invocation causes ${{CC}} to be empty, triggering a build failure as
LDCMD (in Makefile.shared) receives no value.
