Then firefox proceeds with building this bundled jemalloc.
You do not decide what is relevant and what is not. There are guidelines for filling a bug report. We request build.log and emerge --info for reasons. Once this is provided feel free to reopen bug report.

jemalloc has always been bundled, the jemalloc in the mozilla code is heavily modified. As of 55.0 they are moving back to a heavily modified jemalloc-3 so there is nothing we will do to even attempt to split it out and make work with system jemalloc
