[Buildroot] [git commit] package/tesseract-ocr: override neon check

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=789e84b5dacbb39a34fe0ea873f044690a0944a2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Override neon check to avoid the following build failure with uclibc-ng
raised since bump to version 5.0.1 in commit
df3f0c226fccd8d6143b09a1e05a0f5f23587136:

src/arch/simddetect.cpp:61:14: fatal error: sys/auxv.h: No such file or directory
   61 | #    include <sys/auxv.h>
      |              ^~~~~~~~~~~~

It should be noted that a patch to properly fix this build failure was
rejected by upstream as "ARM support without NEON would result in a very
slow Tesseract": https://github.com/tesseract-ocr/tesseract/pull/3717

So, a follow-up patch adding a dependency on !BR2_TOOLCHAIN_USES_UCLIBC
for all CPU architectures or only for ARM without NEON could be
approriate.
