[musl] musl 1.2.2 link error on __libc_malloc with --with-malloc=oldmalloc

[musl] musl 1.2.2 link error on __libc_malloc with --with-malloc=oldmalloc

[daggs]

Greetings,

I seems to encounter an issue when creating a musl libc based cross compiler using crosstool-ng.
the error is as follows:
[ALL  ]      /home/dagg/workspace/crosstool-ng/.build/x86_64-unknown-linux-musl/buildtools/lib/gcc/x86_64-unknown-linux-musl/10.3.0/../../../../x86_64-unknown-linux-musl/bin/ld: obj/src/malloc/oldmalloc/malloc.lo: in function `__libc_malloc':
[ALL  ]      malloc.c:(.text.__libc_malloc+0x0): multiple definition of `__libc_malloc'; obj/src/malloc/lite_malloc.lo:lite_malloc.c:(.text.__libc_malloc+0x0): first defined here

from the looks of it, __libc_malloc is defined in more than one files which are getting linked.
in comparison,in I downgrade musl to 1.2.1, the issue doesn't reproduces.

has anyone encountered it? how can I fix this issue?

Thanks,

Dagg
