[PATCH] include LDFLAGS when linking unit tests

[Tom Guilderson]

When building and running 32 bit x86 unit tests on x86_64 host, linker throws
error:

lib/libjemalloc.so: could not read symbols: File in wrong format

This is caused by LDFLAGS not being passed to unit test linking step, the
following patch fixes this issue.
