MIPS: Avoid a dangling `vfork@GLIBC_2.0' reference
|
|
|
|
This satisfies a symbol reference created with:
|
|
|
|
.symver __libc_vfork, vfork@GLIBC_2.0
|
|
|
|
where `__libc_vfork' has not been defined or referenced. In this case
|
|
the `vfork@GLIBC_2.0' reference is supposed to be discarded, however a
|
|
bug present in GAS since forever causes an undefined symbol table entry
|
|
to be created. This in turn triggers a problem in the linker that can
|
|
manifest itself by link errors such as:
|
|
|
|
ld: libpthread.so: invalid string offset 2765592330 >= 5154 for section `.dynstr'
|
|
|
|
The GAS and linker bugs need to be resolved, but we can avoid them too
|
|
by providing a `__libc_vfork' definition just like our other platforms.
