File 0006-libgcrypt-kdf-Include-compiler-rt.h.patch of Package grub2

Subject: [PATCH 06/12] libgcrypt/kdf: Include compiler-rt.h

There are several functions using the 64bit modulus which is not
natively supported by some 32-bit platforms. Thus, the compiler-rt.h
header has to be included for the software division functions, such as
__moddi3().
