Older toolchains contain an issue with the linker script causing failures when linking tftpd:

tftpd.c:(.text.startup+0x5c): warning: Unable to reach (null) (at 0x00000000)
from the global pointer (at 0x00011a80) because the offset (-72320) is out of
the allowed range, -32678 to 32767.

This is a known issue which has been fixed from 6.x, so disallow on older
toolchains:
