microblaze: Add missing implementation when !__ASSUME_TIME64_SYSCALLS
In commit a92f4e62 ("linux: Add time64 pselect support"), a Microblaze specific implementation of __pselect32() was added to cover the case of kernels < 3.15 which lack the pselect6 system call. This new file sysdeps/unix/sysv/linux/microblaze/pselect32.c takes precedence over the default implementation sysdeps/unix/sysv/linux/pselect32.c. However sysdeps/unix/sysv/linux/pselect32.c provides an implementation of __pselect32() which is needed when __ASSUME_TIME64_SYSCALLS is not defined. On Microblaze, which is a 32-bit architecture, __ASSUME_TIME64_SYSCALLS is only true for kernels >= 5.1. Due to sysdeps/unix/sysv/linux/microblaze/pselect32.c taking precedence over sysdeps/unix/sysv/linux/pselect32.c, it means that when we are with a kernel >= 3.15 but < 5.1, we need a __pselect32() implementation, but sysdeps/unix/sysv/linux/microblaze/pselect32.c doesn't provide it, and sysdeps/unix/sysv/linux/pselect32.c which would provide it is not compiled in. This causes the following build failure on Microblaze with for example Linux kernel headers 4.9: [...]/build/libc_pic.os: in function `__pselect64': (.text+0x120b44): undefined reference to `__pselect32' collect2: error: ld returned 1 exit status Signed-off-by:Thomas Petazzoni <thomas.petazzoni@bootlin.com> Reviewed-by:
