__MATH_TG is only defined for real floating types, since all of the type

No unwind tables are generated, as if -funwind-tables is ignored. If
LTO is disabled, everything works as expected.

The assembler does not allow switching back to .eh_frame once a

The RISC-V ABI does not address this, AFAICS.

But if the translation units are compiled with -funwind-tables, we want
the ltrans "units" to behave the same.

The -funwind-tables and -fasynchronous-unwind-tables options are relevant

Otherwise, dwarf2out_assembly_start may output a ".cfi_sections

Now that we have support for inline subword atomic operations, it is no
longer necessary to link against libatomic. This also fixes testsuite
failures because the framework does not properly set up the linker flags
for finding libatomic.
The use of atomic operations is also independent of the use
