f541d3f18e MDEV-20596 Configure fails with newer CMake 
Fix build error with newer cmake

Fixes the following build error:

CMake Error at cmake/os/Linux.cmake:29 (STRING):
STRING sub-command REPLACE requires at least four arguments.
Call Stack (most recent call first):
CMakeLists.txt:101 (INCLUDE)

CMake Error at cmake/os/Linux.cmake:29 (STRING):
STRING sub-command REPLACE requires at least four arguments.
Call Stack (most recent call first):
CMakeLists.txt:101 (INCLUDE)

The error happens when CMAKE_SHARED_LINKER_{LANG}_FLAGS is not set.
Force the variable to be set to "" as input to prevent this.

2a2ab121b0 MDEV-17703 Add WITH_UBSAN switch to CMake similar to WITH_ASAN 
This can be useful:
UBSAN_OPTIONS=log_path=/some/path

clang users may want to increase stack size in include/my_pthread.h or enable
some optimizations

402c7584a8 MDEV-13785: move defination HAVE_LARGE_PAGES -> HAVE_LINUX_LARGE_PAGES 
HAVE_LARGE_PAGES was always Linux but now there is
HAVE_SOLARIS_LARGE_PAGES in the code base. Innodb was using HAVE_LINUX_LARGE_PAGES
so keep this consistent everywhere.

Test plan:

$ grep Hugepagesize: /proc/meminfo
Hugepagesize:       2048 kB

$ sudo sysctl vm.nr_hugepages=1024
vm.nr_hugepages = 1024
$ sudo sysctl  kernel.shmmax=$(( 2 * 1024 *1024 * 1024 ))
kernel.shmmax = 2147483648

No errors in ouput:

63a205d4a0 Bug#17632386: WITH_ASAN CONFLICTS WITH -WL,--NO-UNDEFINED 
-Wl,--no-undefined (=-z defs) gives linking errors when used with WITH_ASAN.
According to the documentation:
"When linking shared libraries, the AddressSanitizer run-time is not linked,
so -Wl,-z,defs may cause link errors (don’t use it with AddressSanitizer)."

This patch turns off -Wl,--no-undefined if WITH_ASAN is used.

  force %esi register, don't give gcc a choice.
