I am concerned about making the utmpx calls as the default. They should be done only for the MUSL case. |

On the musl libc, utmp is unimplemented. The utmps library by skarnet provides utmpx functionality on musl, but not utmp. This pull request modifies Linux PAM to support user accounting on musl distros that link it to utmps, by using
<utmpx.h>instead of<utmp.h>ifHAVE_UTMPX_His defined inconfig.h.On glibc, utmpx and utmp are aliases, so there is no functional change there.
