libc: regoranize malloc build

2023-08-16T18:16:51+00:00

Create a stdlib/malloc to hold the definition of the malloc interface
(e.g., the Symbol.map file) and make jemalloc a subdirectory.  This will
make it easier to integrate alternative allocators such as snmalloc
while making it clear that the current jemalloc symbols are the FreeBSD
API/ABI (for better or worse).

jemalloc: drop unused .PATH

2023-08-16T18:16:43+00:00

All jemalloc sources are in contrib so don't look for them in the
jemalloc subdirectory.
