manual/configure.txt: fix C++ escaping

For asciidoc, a string like '+these are some words+' will be displayed in
monospace font. Such sequences are identified by searching for a matching
pair of + signs in the same block.

The string 'C++' also contains such + signs. In most cases, this does not
pose a problem and no escaping is necessary. However, if 'C++' occurs twice
in the same block, the + signs will be matched to each other, and asciidoc
formats all text between them as monospaced text. In this case, escaping of
one of these 'C++' occurances is necessary to get the right formatting.

In one place of the manual, there is a sentence that causes such a problem:
    "you only have to tell whether your toolchain supports C++ or not and
    whether it has built-in RPC support. If your external toolchain uses
    the 'uClibc' library, then you have to tell Buildroot if it supports
    largefile, IPv6, RPC, wide-char, locale, program invocation, threads
    and C++."

Commit 082dec8ce4 was based on a patch fixing
this problem in one place of the manual, but was incorrectly changed while
committing.

This patch reverts the incorrect changes in that commit, and solves the
problem correctly.
