Commit 67bf347ba924 ("kbuild: remove PROVIDE() for kallsyms symbols")
introduces the use of scripts/kallsyms with /dev/null as input to
generate the kernel symbols file. This results in getline() returning
ENOTTY as the errno value on macOS hosts. To handle this different
behavior, add a specific #ifdef condition for macOS.
Fixes:
+ scripts/kallsyms --base-relative /dev/null
read_symbol: Inappropriate ioctl for device
make[1]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1
make: *** [Makefile:1172: vmlinux] Error 2
