Boost: correct address model for "s390x" architecture

[pya102]

Added "s390x" to the _b2_address_model function to return "64".

Summary

Changes to recipe: lib/all

Motivation

Boost library fails to build on IBM Z and IBM LinuxONE processors due to recipe defaulting to 32-bits architecture due to the following function:

def _b2_address_model(self):
        if self.settings.arch in ("x86_64", "ppc64", "ppc64le", "mips64", "armv8", "armv8.3", "sparcv9"):
             return "64"

        return "32"

Details

Added "s390x" to the architecture tuple returning "64":

def _b2_address_model(self):
       if self.settings.arch in ("x86_64", "ppc64", "ppc64le", "mips64", "armv8", "armv8.3", "sparcv9", "s390x"):
            return "64"

        return "32"

PR is fine, just double checking something on CI :)

Thanks @pya102 - We don't have a way to test this, but all info I can find online points to that architecture being 64-bit .

[pya102]

Thank you so much for your response.

If interested, IBM provides access to Virtual Machines using s390x architecture to Open Source projects like this one. You can request access using this link: https://community.ibm.com/zsystems/form/l1cc-oss-vm-request/

I look forward to continuing to contribute to the community.
