mozjs: fix linking issues on i586

When building for qemux86 on a x86 host, there's a possibility that the build
will try to link with incorrect libraries. Due to problematic -rpath-link the
linker may try to use host libraries if they are present and are arch
compatible.

+Subject: [PATCH] fix cross compilation on i586 targets
+
+Remove offending -Wl,-rpath-link that may cause host libraries to be picked
+during linking. The patch applies a fix to configure.in. So as not to
+regenerate configure, similar fix is applied there.
