[openssl-dev] [openssl.org #4056] 1.0.2d and Configure issue under X32 (ARFLAGS is architecture name?)

[noloader@gmail.com via RT]

I experienced this issue under X32. X32 provides 32-bit integers,
longs and pointers combined with the richness of x86_64 register set.
Debian has a chroot environment for X32 at
https://wiki.debian.org/X32Port.

It appears ARFLAGS is set to the architecture when using RPATH options
in Configure's $cflags and $ldflags. RPATHS are important (IMHO)
because OpenSSL can get into a situation where /usr/local/bin/openssl
uses /usr/local/lib/libssl.so, but libssl.so uses the system's
/usr/lib/libcrypto.so.

I added a Configure target that provides RPATH options to $cflags
(field 2) and $ldflags (field 6):

    # ./Configure LIST | grep x32
    linux-x32
    linux-x32-rpath
    linux32-s390x

Here's what it looks like (copy and paste from under emacs; ignore the
back slashes):

    "linux-x32-rpath",    "gcc:-mx32 -DL_ENDIAN -O3 -Wall
-Wl,-rpath=/usr/local/ssl\
    /lib::-D_REENTRANT::-Wl,-rpath=/usr/local/ssl/lib
-ldl:SIXTY_FOUR_BIT RC4_CHUNK\
    _LL DES_INT DES_UNROLL:${x86_64_asm}:elf:dlfcn:linux-shared:-fPIC
-mx32:.so.\$(\
    SHLIB_MAJOR).\$(SHLIB_MINOR):::x32",

And below is what it results in, which fails under `make` because `ARFLAGS=m32`.
