PATCH: Re: 971225: bootstrap fails on powerpc-unknown-linux-gnu*

[Franz Sirl]

Hi,

the reported bootstrap fail on Linux/PPC was introduced in rev. 1.3 of
rs6000/sysv4.h by a #undef JUMP_TABLES_IN_TEXT_SECTION. linux.h includes
sysv4.h but didn't override the change.
Eventually this hides a bug in binutils?

Bye,
Franz.
