[Buildroot] [git commit branch/2022.05.x] package/tesseract-ocr: fix aarch64_be build

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=bddf53b7ab05072db580fae99a3ce5673993d6ee
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.05.x

Fix the following aarch64_be build failure probably raised since the
addition of the package:

/home/buildroot/autobuild/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/aarch64_be-none-linux-gnu/10.3.1/../../../../aarch64_be-none-linux-gnu/bin/ld: ./.libs/libtesseract.so: undefined reference to `tesseract::IntSimdMatrix::intSimdMatrixNEON'

Fixes:

Update the comment about _AUTORECONF=YES, list the two patches since
both touch configure.ac
