Adding the -mspe (in addition to -mabi=spe) option helped. It seems that only
few combinations of the -mcpu=8520, -mfloat-gprs=*, -mspe, and -mabi=spe flags
are well tested in GCC.  The following combinations worked:

(1) -mcpu=8540 -msoft-float
(2) -mcpu=8540 -mspe -mabi=spe -mfloat-gprs=single
(3) -mcpu=8540 -mspe -mabi=spe -mfloat-gprs=double
