You may wanna have a look into Ipopt/config.log to see what make the
check fail. Maybe it is a missing -lgomp in --with-pardiso?

Mostly the same: You may wanna have a look into Ipopt/config.log to see
why linking against your Blas library failed. It may show you some
unresolved symbols.

-lgomp should be in LDFLAGS (linker flags), not in CFLAGS or FFLAGS
(compiler flags).
