[PATCH v3 6/7] MIPS: Reword KBUILD_SYM32 documentation for clarity

[Maciej W. Rozycki]

It is currently hard to figure out what the inline documentation for the 
KBUILD_SYM32 option means as it speaks in generic build/ELF format terms 
which can mean just about anything, while the whole point of the option 
is whether kernel symbols can or cannot fit in the 32-bit value range.

Adjust the description accordingly and also quote the more correct 'n' 
rather than 'no' setting (even though all that matters is whether it's 
'y' or not).

-# Automatically detect the build format. By default we choose
-# the elf format according to the load address.
-# We can always force a build with a 64-bits symbol format by
-# passing 'KBUILD_SYM32=no' option to the make's command line.
+# Automatically detect whether to build a 64-bit kernel using symbols
+# limited to 32-bit values, which produces more compact code.  This
+# relies on the kernel image being linked at a 32-bit load address,
+# which we use to infer whether to use this arrangement for symbols.
+# Use 'make KBUILD_SYM32=n' to override this default choice and force
+# 64-bit symbols to be used instead.
