I get the following error:
bison --yacc --name-prefix=__gettext --output
bison: m4 subprocess failed: No such file or directory
make: *** [Makefile:46:
/sources-lfs/glibc-2.27/glibc-build/intl/plural.c] Error 1
make: Leaving directory '/sources-lfs/glibc-2.27/intl'
make: *** [Makefile:215: intl/subdir_lib] Error 2

If I include 'ln -sfv /tools/bin/m4 /usr/bin' as suggested some time
ago, I can compile glibc. In an effort to understand why systemd crashes
and having a message that there is a segfault in glibc while booting, i
tried to recompile all again. Now I can't even compile glibc.
Is this a result of some modification in the tool chain, or is de
documentation not upto date?
