It appeared in commit 21cdc2e77a4ca999 ("fix 32-bit link with gcc")
that linker options must be prefixed by -Wl, when using CC.
So CPU_LDFLAGS is prefixed in rte.lib.mk.
Then commit 815cfb7925bb6de ("fix link of combined shared library using CC")
introduced another prefixing of CPU_LDFLAGS in rte.sharelib.mk,
included in lib/Makefile.
Because CPU_LDFLAGS is an exported variable, the prefixing is done twice.
Initial patch of commit 815cfb7925bb6de had a workaround but it hasn't
been applied in favor of this proper fix.
Now variables are not overriden when prefixing.

The option "-z muldefs" was set only if not using ld directly.
By the way, this option seems to be a useless hack introduced
with shared and combined libraries support (e25e4d7ef16b8aa84de).
The clean approach is to remove it.

If we set EXTRA_CFLAGS=-O0, build fails with following error:
/usr/bin/ld: test: hidden symbol `mknod' in /usr/lib64/libc_nonshared.a(mknod.oS) is referenced by DSO
Fix: link combined shared lib using CC if LINK_USING_CC is enabled.

Only CPU_LDFLAGS is used in mk/rte.sharelib.mk.
It should be LDFLAGS to build the library with correct linkage options.

This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].

The shared libraries built with the current makefile set produce static
libraries rather than actual shared objects. This is due to several missing
options that are required to correctly build shared objects using ld, as well as
a mis-specified -share option (which should be -shared). Switching to the use of
CC rather than LD and fixing the -shared option corrects these problems and
builds the DSOs correctly.
