OpenSSH stalls on configuring

[dslm4515]

In a 32-bit chroot for CMLFS, openssh stalls when executing configure script:

checking whether OpenSSL has NID_X9_62_prime256v1... yes
checking whether OpenSSL has NID_secp384r1... yes
checking whether OpenSSL has NID_secp521r1... yes
checking if OpenSSL's NID_secp521r1 is functional...

Script hangs and never proceeds. Same results with the following:

• openssh-9.5p1, openssl-3.2.0
• openssh-9.5p1, openssl-3.2.1
• openssh-9.5p1, openssl-3.3.0
• openssh-9.7p1, openssl-3.2.1
• openssh-9.7p1, openssl-3.3.0

On my 64-bit PC also running CMLFS, openssh-9.5p1 configures fine with openssl-3.2.0.

Same issue if I use clang or GCC in the 32-bit chroot

For now, build openssh against libreSSL [for 32-bit x86 systems)
