OPENSSL_SMALL_FOOTPRINT

[Manish Patel]

Hi,

  I am trying to upgrade from 1.1.1c to 3.0.8.

However doing so increases the libcrypto.a size tremendously.

Some .so we create increased by 1.6MB, which is ~38% increase.

It increases our final binary size by 1.1M which is ~27% increase
to our previous (using 1.1.1c) binary and very much unacceptable
in our environment.

Above increase is despite of reducing all unused modules as follows:
  no-afalgeng \
  no-aria \
  no-asan \
  no-asm \
  no-async \
  no-autoalginit \
  no-autoerrinit \
  no-autoload-config \
  no-bf \
  no-blake2 \
  no-camellia \
  no-capieng \
  no-cast \
  no-comp \
  no-cms \
  no-crypto-mdebug \
  no-crypto-mdebug-backtrace \
  no-ct \
  no-deprecated \
  no-devcryptoeng \
  no-dgram \
  no-dsa \
  no-dso \
  no-dtls \
  no-dynamic-engine \
  no-ec2m \
  no-ecdh \
  no-ecdsa \
  no-ec_nistp_64_gcc_128 \
  no-egd \
  no-engine \
  no-err \
  no-external-tests \
  no-filenames \
  no-fuzz-libfuzzer \
  no-fuzz-afl \
  no-gost \
  no-heartbeats \
  no-hw \
  no-idea \
  no-makedepend \
  no-md2 \
  no-md4 \
  no-mdc2 \
  no-msan \
  no-multiblock \
  no-nextprotoneg \
  no-pinshared \
  no-ocb \

  no-ktls \
  no-loadereng \
  no-module \
  no-padlockeng \
  no-siv \

  no-trace \
  no-uplink \

I introduced OPENSSL_SMALL_FOOTPRINT, which barely reduced size by ~100KB!
Any ideas?

Thank you
Manish.
