bug#8021: bootstrap failed on solaris10

[Jeff liu]

Hello,

I was ran into a wired issue when running `bootstrap` on solaris10 with 
bash-3.00, 
bash-3.00# ./bootstrap
./bootstrap: syntax error at line 328: `p1=$' unexpected

bash-3.00# uname -a
SunOS pibroch 5.10 Generic_142910-17 i86pc i386 i86pc

Coreutils is cloned from upstream,  I am intend to try it on Solaris for sparse 
file copy through lseek. 



Best Regards,
-Jeff
