Masamichi Takagi 62772c8a24 gencore: Allocate ELF header to heap instead of stack ...

coredump() proceeds as follows:

1. coredump() calls gencore()
2. gencore() allocates ELF header to stack
3. gencore() prepares the core table and record the address of the ELF
   header to the table and return to coredump()
4. coredump() offloads __NR_coredump with the address of the core
   table

This fix prevents the ELF header from getting destroyed in the 3rd
step.
