# Without this patch, the first local include of unwind.h might, with the
# __has_include_next, try to include the one from the system.
# It might be /usr/include/clang/3.4/include/unwind.h
# Because of the #ifndef __CLANG_UNWIND_H, it might never include any declaration
# from the system.

* debian/patches/riscv64-multilib-empty.patch: Adjust riscv64 GCC detector
to also check for existence of crtbegin.o in the default multilib dir,
like most other ports. Fixes FTBFS on riscv64, since on Ubuntu
/usr/lib/gcc/riscv64-linux-gnu/10 exists but is empty (gcc-10-base is
installed, but libgcc-10-dev is not).
