Newer builds of sort include a --debug flag that show you what is going on:
$ printf "CC = gcc\nCC = aCC\nCCFLAGS =\nCC = cc\n" | src/sort --debug
src/sort: using ‘en_US.UTF-8’ sorting rules
CC = aCC

CC = cc

CCFLAGS =
_________
CC = gcc

versus
$ printf "CC = gcc\nCC = aCC\nCCFLAGS =\nCC = cc\n" | LC_ALL=C src/sort
--debug
src/sort: using simple byte comparison
CC = aCC

CC = cc

CC = gcc

You have hit an FAQ:
https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#Sort-does-not-sort-in-normal-order_0021
Your current locale has chosen a collation sequence that ignores blanks
and the equal sign, so sort is sorting correctly. Set LC_ALL in the
environment of sort to a different locale if you want bytewise sorting.
Have a nice day,
