This is the kernel's idea of uts length, not glibc, it is independent
of where you are compiling.  It could be extracted from the kernel
header,
  uts_len := $(shell sed -ne 's/#define __NEW_UTS_LEN //p' include/linux/utsname.h)
but why bother?  The value has been fixed at 64 since at least 2.0 and
is embedded in glibc so it is unlikely to change.  Even if it does
change, it must be upwards so the worst case is fail safe.
