cmake/target.cmake defines macros for the supported platforms, this
commit changes predefined system macros to our own macros.
__linux__ --> OS_LINUX
__APPLE__ --> OS_DARWIN
__FreeBSD__ --> OS_FREEBSD
Under TSan using too much stack requires too much RSS for shadow memory,
and neither of this TSAN_OPTIONS helps:
- history_size=2
- flush_memory_ms=2000
- memory_limit_mb=50000
So instead, decrease allowed limit of the stack size in checkStackSize()
under TSan, to address exessive memory usage for the server compiled
with TSan.
Note, that before this patch 01763_max_distributed_depth test can
increase RSS of the server to 70GiB.
Should fix the following exception under osx:
Stack size too large. Stack address: 0x700001a58000, frame address: 0x700001a53f40, stack size: 540864, maximum stack size: 524288 (version 21.7.1.1)
This commit adds a number of changes to platform-detection and
compile-time directives required to support building ClickHouse on
Solaris-derived systems, most notably illumos.
