uninit.c includes glibc-specific <fpu_control.h> not provided by musl.
Somewhat portable replacement is <fenv.h>, which is available in musl
but requires non-trivial changes to uninit.c.
f2c uses _uninit_f2c() from uninit.c to implement its -trapuv option,
pre-initializiing floating-point variables to NaN and asking FPU to send
SIGFPE whenever NaN value is encountered.
clapack source has already been run through f2c without -trapuv,
so uninit.c code is not used anywhere and can be safely excluded.
