Emit PERLASM_SCHEME to fix 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:
.../crypto/ec/ec_lib.c:74:19: error: unused variable 'EC_version' [-Werror,-Wunused-const-variable]
static const char EC_version[] = "EC" OPENSSL_VERSION_PTEXT;
Remove short-circuit to allow GitMake test to pass

Removing this code allowed GitMake to successfully build and run all the
tests. It was previously breaking because only the first '@' line of test_bn
and other test rules was updated with 'cd $(TEST_D)'.
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.
