[PATCH] libstdc++: Only append "@euro" to locale names for Glibc testing

[Jonathan Wakely]

I doubt we want the @euro suffix anywhere except Glibc-based targets. We
certainly don't want to append "@euro" on Solaris, where this change
flips some tests from UNSUPPORTED to PASS, e.g.
21_strings/basic_string/numeric_conversions/char/to_string_float.cc
It will probably also cause some to flip from UNSUPPORTED to FAIL, which
we'll need to address.

Let's restrict it to Glibc.

Tested x86_64-linux and sparc-solaris11.4.

The testsuite automatically appends "@euro" to "xx.ISO8859-15" locale
names on all targets except FreeBSD, DragonflyBSD, and NetBSD. It should
only be for Glibc, not all non-BSD targets.

libstdc++-v3/ChangeLog:

	* testsuite/lib/libstdc++.exp (check_v3_target_namedlocale):
	Only append "@euro" to ".ISO8859-15" locales for Glibc.
