remove external linkage from __simple_malloc definition

this function is used only as a weak definition for malloc, for static
linking in programs which do not call realloc or free. since it had
external linkage and was thereby exported in libc.so's dynamic symbol
table, --gc-sections was unable to drop it. this was merely an
oversight; there's no reason for it to be external, so make it static.
