[Bug other/30809] New: make install fails due to erroneous nesting of echo commands

["gabriel dot kaelin at visonys dot com" <gcc-bugzilla at gcc dot gnu dot org>]

During installation of gcc-4.1.2 ("gmake MAKE=gmake install") the following
error occurred on our Solaris systems:

echo 'SYSTEM_HEADER_DIR="'"`echo /usr/include | sed -e :a -e "s,[^/]*/\.\.\/,,"
-e ta`"'"' \
        >
/slt/devel/toolsbase/gcc/4.1.2/sparc-sun-solaris2.10/lib/gcc/sparc-sun-solaris2.10/4.1.2/install-tools/mkheaders.conf
sed: command garbled: s,[
/bin/sh: : cannot execute
/bin/sh: /]*/../,, -e ta: not found
gmake[2]: *** [install-mkheaders] Error 1
gmake[2]: Leaving directory
`/var/tmp/gcc_powell_sparc-sun-solaris2.10_23537/objdir/gcc'
gmake[1]: *** [install-gcc] Error 2
gmake[1]: Leaving directory
`/var/tmp/gcc_powell_sparc-sun-solaris2.10_23537/objdir'
gmake: *** [install] Error 2

I've checked the command: 
echo 'SYSTEM_HEADER_DIR="'"`echo /usr/include | sed -e :a -e "s,[^/]*/\.\.\/,,"
-e ta`"'"'

It can be changed to:
echo 'SYSTEM_HEADER_DIR="'`echo /usr/include | sed -e :a -e "s,[^/]*/\.\.\/,,"
-e ta`'"'

I've just omitted the double quotes around the command substitution with
backquotes. That way gcc 4.1.2 would install successfully on my machines.

The command most probably originates from gcc/Makefile.in on line 3786 of 4616,
but I haven't retried compilation with that change.
