utimes: Export utimensat based utimes
sys/time.h has libc_hidden_proto(utimes) which generates the hidden "__GI_utimes" symbol reference, and common/utimes.c has a libc_hidden_def(utimes) which generates the exported "utimes" alias. As part of no-legacy-syscall kernel ABI, Commit 80dc2ed05 "utimes: Use utimensat if arch does not have the utimes syscall" introduced a new wrapper, but missed the corresponding libc_hidden_def, causing Busybox (1.20.0) link to fail (for ARC). Also don't generate a STUB, in that case. ---------------->8------------------- .... touch.c:(.text.touch_main+0xdc): undefined reference to `utimes' touch.c:(.text.touch_main+0x114): undefined reference to `utimes' libbb/lib.a(copy_file.o): In function `copy_file': copy_file.c:(.text.copy_file+0x446): undefined reference to `utimes' collect2: ld returned 1 exit status ---------------->8------------------- Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
