The gdb version in Ubuntu 24.04 fails on our synthetic DWARF because:
- the synthetic DWARF unit has no DW_AT_language
- synthetic types are referenced from a unit that does have DW_AT_language
- this triggers https://sourceware.org/bugzilla/show_bug.cgi?id=32431
Workaround this issue by specifying DW_LANG_C11. This may not be exactly the right meaning, but it should be safe.
Closes #9731
I would like this change because my development system has this gdb version.

This all seems reasonable to me as it updates tools to more recent versions. I'm no DWARF expert, though, so I'll leave this open for a bit in case @alexcrichton or @fitzgen have any stronger opinions about the C11 decision.
