Given the nature of libexec dir that might be nice to have, so we wouldn't 
override libexecdir but just not package it for 32-bit arch.

Just one thing - couldn't there be any situation where libexec program output 
would be different for primary and supplementary architectures? And, BTW, 
looking at glibc, it installs "getconf/POSIX_V6_LP64_OFF64" for 64-bit 
and "getconf/POSIX_V6_ILP32_OFF32" with "getconf/POSIX_V6_ILP32_OFFBIG" for 
32-bit.

Although looking at Debian it doesn't have any of this POSIX_* thing at all.
