[v3 PATCH]: Fix bootstrap failure on powerpc-apple-darwin7.9.0

[Roger Sayle]

The following simple patch fixes the current bootstrap failure on
powerpc-apple-darwin7.9.0.  This issue is that the darwin system
headers define the macro "_T", so this identifier can't be used.
The workaround is to simply rename the problematic use of "_T" in
include/ext/codevt_specializations.h's __iconv_adaptor.

Tested on powerpc-apple-darwin7.9.0 where a bootstrap now progresses
past the current failure.  Ok for mainline?

	* include/ext/codevt_specializations.h (__iconv_adaptor): Use
	identifier _Type instead of _T in template argument.
