[jataylo]

The PR moves to use libtinfo.so.6 on ROCm5.3 and beyond and includes a logic fix in build_common.sh and build_libtorch.sh

pytorch/pytorch#92538

Branch tested on upstream: pytorch/builder@main...jataylo:builder:libtinfo_update_jataylo

This fixes the error message seen for ROCm5.3 eg. in https://ossci-raw-job-status.s3.amazonaws.com/log/10656518264:

We need the version-dependent switch because ROCm5.2 needs libtinfo.so.5, otherwise we get the following message when using libtinfo.so.6 for it:
/usr/bin/ld: /tmp/libtorch/lib/libamd_comgr.so: undefined reference to 'setupterm@NCURSES_TINFO_5.0.19991023'

LGTM. Thanks for testing it, @jataylo!
