Bug #6772 Prebuilt 4.1.7 binaries for Solaris x86 fail on Pentium III

Description:
Attempting to use the downloaded 4.1.7 binary distribution for Solaris 9 on x86.

A simple test gives me:

% /usr/local/mysql/bin/mysql --version
Illegal instruction (core dumped)

On any Pentium III based system; it works fine on Pentium IV based machines.

The binaries are stripped, but I can see from one of the libraries that it was built using the
Studio 9 compiler and -xtarget=native (presumably via the -fast flag). This flag is problematic as it generates cpu-specific optimizations and instructions.

How to repeat:
Try running mysql on a Pentium III based Solaris x86 machine.

Suggested fix:
Don't use -fast, or explicitly add -xtarget=generic.

I tried both mysql-standard-4.1.7-pc-solaris2.9-i386.tar.gz  and mysql-standard-4.1.8-pc-solaris2.9-i386.tar.gz with Solaris 9 x86 
installed on a P3mobile system (within vmware) without any
problems

It still fails for me every time on a PIII system.  And 4.1.8 and 4.1.9 fail as well.

Just for reference, I'm using PIII Xeon 5550MHz (Dell 6350) and PIII 1.4GHz (Sun LX50)
with kernel 112234-11. PIV based systems running the same revision of Solaris work fine.

Bug#9283 was marked as a duplicate of this bug.

BUG#9283 reported similar problems on Solaris 10. We need to double check the compile options on these platforms - most likely the optimization flags need to be adjusted.

The compile flags for the Solaris 8/9/10 x86 binaries indeed contained "-xtarget=native".
They have now been changed to "-xtarget=generic" to support PIII systems as well and to
avoid the "illegal instruction" crash.

The upcoming releases of MySQL (4.0.27, 4.1.15 and 5.0.14) will be built with these flags.

Noted in 4.0.27, 4.1.15, 5.0.14 changelogs.
