scripts, cc/gcc: do not fail on existing symlinks or build.log
If the user builds a toolchain over an existing one, so, without removing
CT_PREFIX_DIR, the build fails as the symlinks already exist, as does the
build.log.
This can also happen (for build.log) if the user first ran in download-
or extract-only.
Patch (with no SoB) originally from:
Phil Wilshire <phil.wilshire@overturenetworks.com>
Modified by me as it did not apply cleanly.

1 # Makefile.in for building crosstool-NG
2 # This file serves as source for the ./configure operation
4 # This series of test is here because GNU make 3.81 will *not* use MAKEFLAGS
5 # to set additional flags in the current Makfile ( see:
6 # http://savannah.gnu.org/bugs/?20501 ), although the make manual says it
7 # should ( see: http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion )
8 # so we have to work it around by calling ourselves back if needed
10 # So why do we need not to use the built rules and variables? Because we
11 # need to generate scripts/crosstool-NG.sh from scripts/crosstool-NG.sh.in
12 # and there is a built-in implicit rule '%.sh:' that has neither a pre-requisite
13 # nor a command associated, and that built-in implicit rule takes precedence
14 # over our non-built-in implicit rule '%: %.in', below.
16 # CT_MAKEFLAGS will be used later, below...
18 # Do not print directories as we descend into them
19 ifeq ($(filter --no-print-directory,$(MAKEFLAGS)),)
20 CT_MAKEFLAGS += --no-print-directory
23 # Use neither builtin rules, nor builtin variables
24 # Note: dual test, because if -R and -r are given on the command line
25 # (who knows?), MAKEFLAGS contains 'Rr' instead of '-Rr', while adding
26 # '-Rr' to MAKEFLAGS adds it literaly ( and does not add 'Rr' )
27 ifeq ($(filter Rr,$(MAKEFLAGS)),)
28 ifeq ($(filter -Rr,$(MAKEFLAGS)),)
