science/rdkit: fix build on GCC architectures

[pkubaj]

Summary

This port needs new GCC to build.

It also adds -mpopcnt to *FLAGS, which breaks build on non-x86. Since it optimizes for the host CPU, don't enable it.

[pkubaj]

Fix packaging.

[pkubaj]

Correct PLIST_SUB.

wouldn't it make more sense to use NON_PPC64 here? as you are not installing them when the architecture is ppc64.

science/rdkit/Makefile

ARCH is defined after bsd.port.options.mk, no need to do the pre/post thing.

[pkubaj]

Don't include bsd.port.pre.mk, bsd.port.options.mk is enough.

Also the .if is not exclusive to powerpc64, but to all big-endian architectures. Since there's no ports variable for endianness, we need to list all architectures.

Changed to LE, since the issue is about endianness.

[mat]

"LE" is pretty generic, LITTLE_ENDIAN would probably be better.
