Subject: [PATCH] Undef _TIME_BITS along with _FILE_OFFSET_BITS on Linux
On 32-bit glibc>=2.34 systems using 64bit time_t build fails because
_FILE_OFFSET_BITS is undefined here but _TIME_BITS is still set to 64
Fixes
```
/usr/include/features-time64.h:26:5: error: "_TIME_BITS=64 is allowed
only with _FILE_OFFSET_BITS=64"
| # error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
| ^

Subject: [PATCH] libsanitizer: also undef _TIME_BITS in
sanitizer_procmaps_solaris.cpp
Upstream commit
https://github.com/llvm/llvm-project/commit/26800a2c7e7996dc773b4e990dd5cca41c45e1a9
of LLVM added a #undef _TIME_BITS in
libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp to
fix the build on 32-bit Linux platforms that have enabled 64-bit
time_t using _TIME_BITS=64.
Indeed, _TIME_BITS=64 can only be used when _FILE_OFFSET_BITS=64, but
sanitizer_platform_limits_posix.cpp undefines _FILE_OFFSET_BITS before
including any header file. To fix this, the upstream fix was to also
undef _TIME_BITS.
This commit simply does the same in sanitizer_procmaps_solaris.cpp,
which also gets compiled under Linux (despite what the file name
says). In practice on Linux hosts (where _TIME_BITS=64 matters),
sanitizer_procmaps_solaris.cpp will expand to nothing, as pretty much
the rest of the file is inside a #ifdef SANITIZER_SOLARIS...#endif. So
the #undef _FILE_OFFSET_BITS and #undef _TIME_BITS are only here
before including sanitizer_platform.h, which will set the
SANITIZER_LINUX/SANITIZER_SOLARIS define depending on the platform.
Fixes:
