Comment (by egall@…):

 r122003 tried to address this, but it just leads to the following:

 }}}
 And then it fails with the same error.
 Personally I would have tried one or both of the following:
 {{{
 if {[string match *clang* ${configure.compiler}]} {
     configure.cflags-append -integrated-as
 }
 }}}
 and/or:
 {{{
 if {[string match *clang* ${configure.compiler}]} {
     configure.env-append CCAS="${configure.compiler}"
     # or maybe:
     configure.env-append AS="${configure.compiler} -cc1as"
 }
 }}}
