I suspect this is a regression from bug 1351109. On my machine, /usr/bin/ld (not gold) is used to link libxul, js, etc. This occurs with and without --enable-gold (not using --enable-release). On the current tip of the beta repo (009589ce), ../../build/unix/gold/ld is used when linking. On central, /usr/bin/ld is invoked. Looking at code in toolchain.configure, the output of configure (checking for ld... gold), and what's in config.status, configure finds gold. But for whatever reason the build system doesn't actually invoke it.
Here is a diff of config.status before and after d0e782180741fa86dd13bb2a2d35ee8b361020d9: --- good 2017-07-24 18:12:41.449546441 -0700 +++ bad 2017-07-24 18:13:19.904689560 -0700 @@ -192 +192 @@ - 'EXPAND_LIBS_ORDER_STYLE': 'section-ordering-file', + 'EXPAND_LIBS_ORDER_STYLE': 'linkerscript', @@ -267 +266,0 @@ - 'LD_IS_BFD': '', @@ -284,0 +284,4 @@ + 'LINKER_LDFLAGS': [ + '-B', + '/home/gps/src/firefox/objdir/build/unix/gold', + ], @@ -800 +803 @@ - 'OS_LDFLAGS': '-lpthread -Wl,-z,noexecstack -Wl,-z,text -Wl,--build-id -B /home/gps/src/firefox/objdir/build/unix/gold', + 'OS_LDFLAGS': '-lpthread -Wl,-z,noexecstack -Wl,-z,text -Wl,--build-id', LINKER_LDFLAGS isn't used. So the loss of -B from OS_LDFLAGS looks like the bug here.
Looks like it disappear during the review phase. Too bad, this is just the most important part :p
