Bug report

Bug description:

For the emscripten build, during building of the python executable, all theLIBHACL_*_LIB_SHARED are used as linker flags, however theLIBHACL_HMAC_LIB_SHARED flag contains objects that are already contained in otherLIBHACL_*_LIB_SHARED flags. This happens, because LIBHACL_MD5_OBJS, LIBHACL_SHA1_OBJS, LIBHACL_SHA2_OBJS, LIBHACL_SHA3_OBJS and LIBHACL_BLAKE2_OBJS are all included inLIBHACL_HMAC_LIB_SHARED throughLIBHACL_HMAC_OBJS via the Makefile.pre.in file.

The configure script then setsLIBHACL_HMAC_LDFLAGS=LIBHACL_HMAC_LIB_${LIBHACL_LDEPS_LIBTYPE} which for a shared emscripten build leads to duplicate dependencies in the final build command which leads to duplicate symbols.

Since I don't know the purpose of the object file references in theLIBHACL_HMAC_OBJS, I do not feel comfortable just removing them, even though that change fixes the emscripten build.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux
