On some gcc - based Linux devkits like older Fedora with gcc 14, the build on Linux x86_64 fails with --enable-linktime-gc set.

Error output :
support_native_java.desktop_libfontmanager_BUILD_LIBFONTMANAGER_run_ld :

/devkits/x86_64-linux-gnu-to-x86_64-linux-gnu-fedora27-gcc14.2.0/bin/../lib/gcc/x86_64-linux-gnu/14.2.0/../../../../x86_64-linux-gnu/lib/../lib64/libstdc++.a(eh_throw.o)(.note.stapsdt+0x14):
error: relocation refers to local symbol ".text.__cxa_throw" [5], which is defined in a discarded section

Reason seems to be that some toolchains eliminate __cxa_throw which is still referenced by other sections.
We could keep this wrongly eliminated symbol by adding some linker flags.
