We use the conditions currently expressed in the gcc version choice. We leave the musl vs mips64 conditions in gcc, because the "fault" really is on gcc, which does not recognise the mips64+musl tuples, so the fix lies within gcc, and the current conditions are fitting.

|
The Ingenic XBurst is a MIPS32R2 microprocessor. It has a
|
|
bug in the FPU that can generate incorrect results in
|
|
certain cases. The problem shows up when you have several
|
|
fused madd instructions in sequence with dependant
|
|
operands. This requires the -mno-fused-madd compiler option
|
|
to be used in order to prevent emitting these instructions.
