Problem at building texinfo-4.13a

[John Taylor]

Hello,

I'm trying to cross-compile texinfo-4.13a. The host system is 
i686-unknown-linux-gnu. The target system is x86_64-unknown-linux-gnu. I 
configured texinfo with the following arguments: --prefix=/usr 
--build=i686-unknown-linux-gnu --host=x86_64-unknown-linux-gnu --disable-nls. 
After having issued "make", I get the following error message:

#

I can get rid of this problem only if I run "make -C tools/gnulib/lib" before 
issuing "make". Is that the normal and recommended way to proceed or is it a bug?

Thanks.
