[PATCH, libstdc++]: Fix static linking failure on alphaev68-pc-linux-gnu

[Uros Bizjak]

Hello!

The fix for PR52689 caused following testsuite failure on
alphaev68-pc-linux-gnu:

Running target unix
FAIL: libmudflap.c++/pass41-frag.cxx (-static) (test for excess errors)
WARNING: libmudflap.c++/pass41-frag.cxx (-static) compilation failed
to produce executable

From the testsuite log:

This happens in #ifdef _GLIBCXX_LONG_DOUBLE_COMPAT protected code.

Following partial revert fixes the failure:

2012-04-04  Uros Bizjak  <ubizjak@gmail.com>

	Partially revert:
	2012-03-28  Benjamin Kosnik  <bkoz@redhat.com>

	PR libstdc++/52689
	* src/c++98/compatibility-ldbl.cc: Guard with PIC

Tested on alphaev68-pc-linux-gnu, approved in the PR audit trail by
Benjamin, committed to SVN.

Uros.
