In functions that modify sp, debug and unwind information should
be located by fp instead of sp, and the conversion is completed
through FORCE_FRAME_POINTER. With gcc -Os, FORCE_FRAME_POINTER is
optimized away, and the modified sp is still used, causing a
segmentation fault in the recvfrom().
Adding a meaningless assembly instruction to use the return value
of FORCE_FRAME_POINTER to prevent it from being deleted.

The _start symbol does not necessarily have to be on the first page of
the application. But the __ehdr_start symbol is always at address zero
for PIE binaries.

The LLVM linker seems to be quite clever. When resolving relocations,
accesses to the GOT are potentially replaced by PC relative addressing
to the requested symbol. This breaks the old method of calculating the
load address by using an unrelocated GOT entry value. Instead, rely on
__ehdr_start having a link address of zero.

Clang-19 defines NAN in <float.h>. Check if NAN is already defined to

While building software that sets _POSIX_C_SOURCE=200809L and uses
stat.st_mtim for ARM, it was noticed that st_mtim was not defined.
This seems to be because common/bits/stat.h was picked up, which does
not take __USE_XOPEN2K8 as a reason to enable st_mtim and related
fields. This appears to be an oversight, and porting the check from
common-generic/bits/stat.h to other architectures does indeed fix the
build issue.
This patch is based on commit 50bd6d06e ("Fix memory corruption due to
struct stat field").

- Fallback to __NR_stat syscall in ld.so if we use 4.x kernel headers.
4.x kernel doesn't support 64-bit time so we can use old syscall
- Add preprocessor conditions to have fstat64 and fstatat64 in libc
with old kernel headers

ARMv8 has particular restrictions which coprocessor can be used and as
such these instructions, which were likely used for backwards
compatibility purposes, cannot be used on ARMv8. We solve this by
checking for ARMv8 and then using the corresponding mnemonics which were
placed in comments alongside the instructions causing issues.
Fixes the following errors:
.../setjmp.S:59:6: error: invalid operand for instruction
stc p11, cr8, [r12], #68
^
.../setjmp.S:62:6: error: invalid operand for instruction
mrc p10, 7, r2, cr1, cr0, 0

- Include sys/types.h instead of asm/types.h
to prevent types conflict for uClibc typedefs and kernel headers
typedefs.
- Cast 3rd arg of utimensat_time64 syscall to integer type
to avoid compiler's -Wint-conversion error. The error was found
during uClibc compilation for mips32.
