Ok, that doesn't tell much, but at least a bit...
Compilation seems to work, but running the conftest supposed to print
sizeof(long) presumably fails, I guess due to a runtime linker error.
(You seem to have libomalloc installed system-wide; unfortunately stderr
is redirected to /dev/null.)
Looking closer at Singular's top-level 'configure', it's quite
surprising that test (and others) didn't fail before, AFAIK.

I made a patch that may enlighten us regarding the error, and should
bring you past the error with sizeof(long)!=sizeof(void*) at least.
Copy the attached patch into build/pkgs/singular/patches/, then do
./sage -i -s singular
Even if that succeeded, please first again make a copy of the newly
generated config.log from the temporary Singular build directory as
before (and post it) before proceeding.
In case installing the Singular package now worked, you can continue
building Sage by simply typing 'make' again (or 'make -jN` with N being
the number of threads/jobs, but you'll presumably know).
Good luck!
