musl: ignore a false-positive warning in __rem_pio2_large.c Gcc 12.1.1 warns that in __rem_pio2_large() - code which we take directly from Musl - The local variable fq[0] may be used before set. This shouldn't happen, because the fq[] array is set by a for loop immediately before being used. There's one snag that gcc 12.1.1 correctly caught, however - this loop will not do anything if jz, its start, is <0. However, this is an internal function that we assume is called with correct parameters, and "prec" with the right values will lead to one of the numbers in init_jk[] to be used to initialze jz, and these are all positives. Since I don't want to modify the musl code, let's just ignore the warning in the Makefile.
