Brad King 4729547a5b XL: Fix link flags for executables on Linux with XL compilers
Use "-Wl,-export-dynamic" with XL to match the "-rdynamic" flag used
with GNU-like compilers.

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Brad King af14f1f2c3 Remove GNU-specific flags from Linux.cmake
We remove the shared library compile/link flags "-fPIC" and "-shared"
because they are not provided by all compilers on Linux.  This allows us
to drop code from the Linux-XL-*.cmake files that erases the bad flags.
All other supported compilers already provide their correct flags for
Linux in their own platform information files.

Brad King 1f06c33f8e Drop -rdynamic from Linux build rules
This is a GNU-specific option that should not be specified for all
compilers on Linux.  It tells the GNU compiler to pass -export-dynamic
to the linker to export symbols from executables for use by plugins.
Since we provide the ENABLE_EXPORTS target property to do the same thing
in a cross-platform way, there is no need to pass -rdynamic always.

Since the option is not useful for GNU tools and breaks other tools on
Linux we simply remove it from CMAKE_SHARED_LIBRARY_LINK_<lang>_FLAGS.
This also allows us to stop setting the variable in other Linux compiler
files just to erase the bad flag.

See issue #9985.

Brad King b5e558e291 Fix XL C++ compiler flags on Linux
In Platform/Linux.cmake we add GNU flags as default for the platform
which breaks non-GNU compilers.  Later we should refactor these flag
files to put compiler-specific flags only in files loaded for each
compiler.  Until then this commit fixes the XL C++ compiler flags on
Linux by erasing the GNU flags.  See issue #9469.
