[ptxdist] [PATCH] open62541: disable link-time optimization

[Roland Hieber]

With gcc 13.2.1 arm-v7a-linux-gnueabihf, the LTO wrapper sometimes
throws internal compiler errors when calling PTXdist without -j:

    [ 96%] Linking C shared library bin/libopen62541.so
    lto1: internal compiler error: in get_token, at opts-common.cc:2123
    0x7f683dce6249 __libc_start_call_main
            ../sysdeps/nptl/libc_start_call_main.h:58
    0x7f683dce6304 __libc_start_main_impl
            ../csu/libc-start.c:360
    Please submit a full bug report, with preprocessed source (by using -freport-bug).
    Please include the complete backtrace with any bug report.
    See <https://gcc.gnu.org/bugs/> for instructions.
    lto-wrapper: fatal error: /opt/OSELAS.Toolchain-2023.07.1/arm-v7a-linux-gnueabihf/gcc-13.2.1-clang-16.0.6-glibc-2.37-binutils-2.40-kernel-6.3.6-sanitized/bin/arm-v7a-linux-gnueabihf-gcc returned 1 exit status
    compilation terminated.

Disable LTO (CMake calls it Interprocedural Optimization) for now.
