libopenssl: bump version to 1.1.1a

libopenssl: bump version to 1.1.1a

- use BR2_TOOLCHAIN_HAS_UCONTEXT
    This is used to set -DOPENSSL_NO_ASYNC if needed.

- apply the CFLAGS correctly when compiling with -Os (bugfix).

- use -latomic when needed
    This fixes the build for br-sparc-uclibc-2018.05

- don't use madvise() if no MMU
    Trying to do so results in undefined reference to madvise() as
    it is not available on uclibc without MMU.
    The original openssl code checks if a macro used in the madvise call
    is defined. The problem comes from the fact that the code in
    crypto/mem_sec.c also includes a kernel header defining the same macro
    unconditionally. Thus the check is always true in that case.
    Upstream: https://github.com/openssl/openssl/pull/8089

- don't compile test/fuzzers
    These binaries introduced with 1.1.x sometimes do not compile.
    This is the case with the br-arm-cortex-m4-full toolchain

- don't build ocsp daemon if no MMU.
    Patch from  Richard Levitte.

- correctly enable cryptodev engine
    Thanks to Arnout Vandecappelle for spotting this.

- remove all parallel build patches (openssl build-system changed)

- rebased 0001-Dont-waste-time-building-manpages-if-we-re-not-going.patch
  to apply to Configurations/unix-Makefile.tmpl (Makefile template)

- removed 0002-cryptodev-Fix-issue-with-signature-generation.patch
  (upstream applied)

- rebased 0003-Reproducible-build-do-not-leak-compiler-path.patch to
  apply to crypto/build.info (Makefile template)

- fix musl/uclibc build failure, use '-DOPENSSL_NO_ASYNC'

- remove legacy enable-tlsext configure option

- remove target/host libdir configure options, fixes openssl.pc installation
  path, fixes wget compile

- change legacy INSTALL_PREFIX to DESTDIR

- remove 'libraries gets installed read only, so strip fails'
  workaround (not needed anymore)

- change engine directory from /usr/lib/engines to
  /usr/lib/engines-1.1

- change license file hash, no license change, only the following
  hint was removed:

    Actually both licenses are BSD-style Open Source licenses.
    In case of any license issues related to OpenSSL please
    contact openssl-core@openssl.org.
