No.  As I've explained earlier this week, -msoft-float code is simply
not link-compatible with -mhard-float code.

Right.  What do people mean by "default configuration"?  The primary
interest in MIPS these days is as an embedded platform, and the main
bare-metal targets (mips-elf, mips64-elf mipsisa32-elf, mipsisa64-elf)
all have -msoft-float multilibs.  You don't have to do anything special
to get them.
