This point is trickier than I thought, my two hacks work only when
I use 'rm' for the main bodyfont style but it do no longer work when
I try to set 'ss' as main style because with

   \undefinevalue{@f at st@rm}%

I'm able to use the sans style as main font but the math setting is
now ignored and with

   \undefinevalue{@f at st@ss}%

I get the right math font and it's no longer possible to use a different
style for the main font.
