This is running 2 git processes in parallel, which, if unlucky can cause
either of them to fail with "File already exists" error.
cmake has caught up and since version 3.18 it started supporting
CPACK_RPM_POST_TRANS_SCRIPT_FILE, something we've supported for
two years and cmake 2.8.11. Both implementation add %posttrans tag
and rpmbuild gets confused.
Disable our implementation for cmake 3.18+
It was only from CMake-3.14.0 that CMAKE_REQUIRED_LINK_OPTIONS
was used in CHECK_CXX_SOURCE_COMPILES. Without this, it could be
the case (as was on OSX) that a flag was never checked in
CHECK_CXX_SOURCE_COMPILES, the CHECK successfully passed, but
failed at link time.
As such we use CMAKE_REQUIRED_LIBRARIES to include the flags to check
as its compatible enough with the cmake versions for non-Windows
compilers/linkers.
Tested on x86_64 with:
* 3.11.4
* 3.17.4
Corrects: 7473e1841c
In the future:
* cmake >=3.14.0 can use CMAKE_REQUIRED_LINK_OPTIONS
* cmake >=3.18.0 can use CHECK_LINKER_FLAG (with policy CMP0057 NEW)
(e.g: commit c7ac2deff9a2c965887dcc67cbf2a3a7c3e0123d)

means that this path already exists, which is not necessarily the case
for make install. Create it `mkdir -p` style.
Largely based on MySQL commit

BUG#24566529: BACKPORT BUG#23575445 TO 5.6
(cut)
Also, the PTR_SANE macro which tries to check if a pointer
is invalid (used when printing pointer values in stack traces)
gave false negatives on OSX/FreeBSD. On these platforms we
now simply check if the pointer is non-null. This also removes
a sbrk() deprecation warning when building on OS X. (It was
before only disabled with building using XCode).
Removed execinfo path of MySQL patch that was already included.
sbrk doesn't exist on FreeBSD aarch64.
Removed HAVE_BSS_START based detection and replaced with __linux__
as it doesn't exist on OSX, Solaris or Windows. __bss_start
exists on mutiple Linux architectures.
Tested on FreeBSD and Linux x86_64. Being in FreeBSD ports for 2
years implies a good testing there on all FreeBSD architectures there
too. MySQL-8.0.21 code is functionally identical to original commit.
