Installation of Diffutils

Install Diffutils by running the following commands:

LDFLAGS=-static CPPFLAGS=-Dre_max_failures=re_max_failures2 \
    ./configure --prefix=$LFS/static --disable-nls &&
make &&
make install

Command explanations

CPPFLAGS=-Dre_max_failures=re_max_failures2: The CPPFLAGS variable is a variable that's read by the cpp program (C PreProcessor). The value of this variable tells the preprocessor to replace every instance of re_max_failures it finds by re_max_failures2 before handing the source file to the compiler itself for compilation. This package has problems linking statically on systems that run an older Glibc version and this construction fixes that problem.
