Pass -fno-lto unconditionally
At least when building the libreoffice rpm on Fedora 33, the relevant -flto...
flags are passed in via the global CFLAGS/CXXFLAGS, and no --enable-lto
configure option is given. That caused this library to be built with LTO there,
which in turn caused at least aarch64 to fail the %check step with

The easiest fix appears to pass -fno-lto unconditionally: For one, both GCC and
Clang appear to support it since before our baseline versions (GCC: baseline
7.0.0, presumably supported since <https://gcc.gnu.org/git/?p=gcc.git;a=commit;
h=d7f09764d7bc66b9997c811c22e11efc87b44792> "Merge lto branch into trunk" in
releases/gcc-4.5; Clang: baseline 5.0.2 (at least on Linux), presumably
supported since <https://github.com/llvm/llvm-project/commit/
10d0868efb320fc33ced13b0abeea7070cd41635> "Driver: Support -fno-lto" in
releases/3.0.x). For another, the other (few) places in the code that check
ENABLE_LTO appear not to be relevant at least for that Fedora 33 rpm build, so
there appears to be no incentive to make that build configure --enable-lto as an
alternative to this fix.
