(Apparently didn't get successfully delivered from the list to me; thanks
 for sending a copy.)

Looking at AMPL's linux32 demo, I get this list of missing functions:
 __divdi3
 __fpu_control
 __isinf
 __isinfl
 __isnanl
 __strtod_internal
 fedisableexcept
 feenableexcept
 pthread_rwlockattr_setkind_np

The first indicates that it may be necessary to add libgcc_s.so.1 to
LD_PRELOAD.
The rest are missing from musl for ABI compat.
ampl and minos are "for GNU/Linux 2.2.5", so may use the 32-bit IO abi.
__is* can be trivially implemented.
__strtod_internal is a version of strtod with an extra int that's expected
to be 0 (per LSB); no idea what that's for.

HTH,
