While trying to build the default Chapel config to test another feature, I found a compatibility issue with Alpine

/usr/lib/gcc/x86_64-alpine-linux-musl/14.2.0/../../../../x86_64-alpine-linux-musl/bin/ld: /home/cloud-user/chapel/third-party/jemalloc/install/host/linux64-x86_64-gnu/lib/libjemalloc.a(jemalloc.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE
/usr/lib/gcc/x86_64-alpine-linux-musl/14.2.0/../../../../x86_64-alpine-linux-musl/bin/ld: failed to set dynamic section sizes: bad value

I think the reason we don't hit this in our nightly portability testing is that we normally use the quickstart config, not the default config. This issue is with the bundled host jemalloc
