Replace curly braces with double quotes for reinplace regex.

post-configure {
     if {[variant_isset universal]} {
         foreach arch ${universal_archs} {
           reinplace -E "s|-dynamiclib|-dynamiclib -arch ${arch}|"  $ 
{worksrcpath}/libtool
         }
     } else {
         reinplace -E "s|-dynamiclib|-dynamiclib -arch $ 
{build_arch}|"  ${worksrcpath}/libtool
     }
}
