Not really...

I found a sed expression in ltmain.sh which seems to set libdir with libdir from libstdc++.la
"eval libdir=`$SED -n -e 's/^libdir=\(.*\)$/\1/p' $func_resolve_sysroot_result`"

Then the sysroot is appended right after that:
func_append newdependency_libs " ${lt_sysroot:+=}$libdir/$name"

So I tried to find from where the sed expression come from.
And I found lt_aix_libpath_sed in configure which is use to set lt_cv_aix_libpath__CXX.

"lt_cv_aix_libpath__CXX=`dump -H conftest$ac_exeext 2>/dev/null | $SED -n -e "$lt_aix_libpath_sed"`"

So I added lt_cv_aix_libpath__CXX in THRIFT_CONF_OPTS.

In not sure if we need to do that for other architecture/toolchain.

I hope this will further investigation.
