glibc-2.2.1 build in seperate directory

[aldomel]

Hello,

There is a problem when building glibc in a directory seperate from 
the source. The make process wants to write to the source directory 
here and during the makeinfo:

make  -C manual subdir_lib
make[2]: Entering directory `/mnt/hda/packages/glibc-2.2.1/manual'
gawk -f texis.awk intro.texi errno.texi memory.texi ctype.texi string.texi chars
et.texi locale.texi message.texi search.texi pattern.texi io.texi stdio.texi lli
o.texi filesys.texi pipe.texi socket.texi terminal.texi syslog.texi math.texi ar
ith.texi time.texi resource.texi setjmp.texi signal.texi startup.texi process.te

/bin/sh: texis.T: Read-only file system
make[2]: *** [texis] Error 1

and later in the install process:

AWK=gawk /bin/sh libc-texinfo.sh 'intro.texi errno.texi memory.texi ctype.texi s
