Dear Maintainer,

The apbs package has ftbfs on riscv64:

```

The full buildd is here:

https://buildd.debian.org/status/fetch.php?pkg=apbs&arch=riscv64&ver=3.4.1-3&stamp=1654099965&raw=0

And I refer to here[0], becasue the fpu_control.h on riscv64 does not
have these macroes are defined, so I am intend to add these macroes in
uninit.c by manual.

Tha patch attached is fix the issue and it is build ok on localy.
