2021-06-20linux-user: Use public sigev_notify_thread_id member if availableMichael Forney
_sigev_un._tid is an internal glibc field and is not available on musl libc. The sigevent(7) man page and Linux UAPI headers both use sigev_notify_thread_id as a public way to access this field. musl libc supports this field since 1.2.2[0], and glibc plans to add support as well[1][2]. If sigev_notify_thread_id is not available, fall back to _sigev_un._tid as before.

2021-06-20linux-user: Fix incorrect use of feature-test-macrosMichael Forney
The _POSIX_C_SOURCE and _XOPEN_SOURCE macros are used by the application to indicate to libc which declarations it should expose. Since qemu does not define them anywhere, it does not make sense to check their value. Instead, since the intent is to determine whether the host struct stat supports the st_*tim fields, use the configure test result which does exactly that.

2021-06-15linux-user: Disable static assert involving __SIGRTMAX if it is missingMichael Forney
This check is to ensure that the loop in signal_table_init() from SIGRTMIN to SIGRTMAX falls within the bounds of host_to_target_signal_table (_NSIG). However, it is not critical, since _NSIG is already defined to be the one larger than the largest signal supported by the system (as specified in the upcoming POSIX revision[0]). musl libc does not define __SIGRTMAX, so disabling this check when it is missing fixes one of the last remaining errors when building qemu.

Turns out there are several errors: target_ulong is the size of the target register, whereas abi_ulong is the target 'unsigned long' type. Not a big deal here, since we only support 64-bit s390x, but not correct either. In target_sigcontext and target ucontext, we used a host pointer instead of a target pointer, aka abi_ulong.
