LinuxIntelEnv.Set.sh -> LinuxX86Env.Set.sh

Hi,

For those who build on Linux i386/x86 platform:

CWS configure20 renames LinuxIntelEnv.Set/LinuxIntelEnv.Set.sh to 
LinuxX86Env.Set/LinuxX86Env.Set.sh for consistancy reasons - there are even 
non-intel processors that implement the instruction set ;-)  Similar move 
happend before on the x86-64 platform when LinuxAMDEnv.Set/LinuxAMDEnv.Set.sh 
was renamed to LinuxX86-64Env.Set/LinuxX86-64Env.Set.sh.

See also http://www.openoffice.org/issues/show_bug.cgi?id=71887 .

Please update your build scripts, etc. :-)

Thank you,
Jan
