[Tarantool-patches] [PATCH v2 luajit 0/2] Fix LuaJIT tests for old libc versions

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

This patch set consists of 2 patches:
The first allows the use of tags with number values in the LuaJIT-tests
suite runner <test.lua>. This is required for the second patch -- it
skips the `strtod parsing` test in <tonumber_scan.lua> for libc versions
older than 2.19, due to the bug [1] in it.

Branch:
https://github.com/tarantool/luajit/tree/skaplun/fix-luajit-tests-centos7
PR in the Tarantool with tests enabled:
https://github.com/tarantool/tarantool/pull/10824

Only sysprof-related tests are failing, this will be fixed in the
separate patch-set.

Changes in v2:
* Parse -E of #include <gnu/libc-version.h> instead of trying to run
  or parse the name of the libc.so.6 to determine its version.
* Typo fixes
