Hello,

When only minimal symbol information is available, the symbol "malloc", 
which is found in a data section because it's a descriptor, gets turns 
into a 32-bit int variable.  Consequently, an attempt to call "malloc" 
is turned into to jump to the code designated by that 32-bit integer 
value found at malloc.

This patch avoids that problem entirely by specifying that on PPC64 
GNU/Linux, the "malloc" function has the name ".malloc" (which is really 
the function's start address).

ok?
Andrew
