* config.gcc (i[34567]86-*-solaris2*): Don't include
i386/t-crtstuff here.
Move extra_parts, i386/t-sol2 in tmake_file to libgcc/config.host.

PR bootstrap/33100
* configure.ac (i?86-*-solaris2.1[0-9]*): Only include
i386/t-crtstuff if linker supports ZERO terminator unwind entries.
* configure: Regenerate.
* config.host (i[34567]86-*-solaris2*): Move i386/t-sol2 in
tmake_file here from gcc/config.gcc.
Move extra_parts here from gcc/config.gcc.
* config/i386/t-sol2: Move here from gcc/config/i386.
Use gcc_srcdir instead of srcdir.
