Build the PS1 target hard-float again

[rixnobis]

Reverts #5. Since #6, string.format no longer converts to double, and liblua built without -msoft-float disassembles identically to the soft-float build: 0 cop1 instructions, no soft-float helper calls (abed030, before #5 and #6, had 4). The flag now only buys 29 "uses -msoft-float" ld warnings in psyqo-lua's hello example, whose exe is byte-identical either way.

Discussion on pcsx-redux/nugget#62, which drops its own soft-float change.
