Comment (by SimonKing):
For the record: When building Sage with the gcc spkg (modified to support
loop optimization and lto) and `-O2 -march=native -flto` then Singular
failed to build (the linker produced an error). Then, I removed `-flto`
and manually installed the Singular spkg. Finally, I reinstated `-flto`
and successfully built the rest of Sage.
Anyway, I found no problem in building Lcalc or zn_poly or ratpoints. I
did not do run the test suite yet, because technically the installation
isn't over: The reference manual is now being built.
