Summary: oprofile fails to link when --with-binutils option is used.

Initial Comment:
If 'configure' is executed with '--with-binutils' option, then 'make' fails during linkage stage.

For example, suppose that 'configure' is ran like that:

./configure --with-kernel-support --with-binutils=/usr

then when 'make' is ran, it fails with the following message:

g++ -W -Wall -fno-common -ftemplate-depth-50 -g -O2 -I /usr/include /usr/lib -Wl,-R -Wl,/usr/lib -o opimport opimport.o  -L/home/dima/a/down/oprofile-0.9.4/libabi libabi.a ../libdb/libodb.a ../libopt++/libopt++.a ../libutil++/libutil++.a ../libutil/libutil.a /usr/lib/libpopt.so -liberty -ldl  
/usr/bin/ld: /usr/lib: No such file: File format not recognized
collect2: ld returned 1 exit status
make[3]: *** [opimport] Error 1

(note: it was unnecessary to ran 'configure' above with '--with-binutils' option in that particular case because binutils headers and libraries were located in a standard place and 'configire' could have found it without the option - the example is just a simulation of a case when binutils' headers/libraries are located in a non-standard place and '--with-binutils' is required).

The problem occurs because path to binutils' libraries is passed to g++ without '-L' switch - preceding a first occurrence of '/usr/lib' above with '-L' solves the problem.

Thanks for reporting this problem.  The --with-binutils configure option
used to work not so long ago, and I determined that the point at which it
broke was when we introduced the use of libtool to our project.  I
contacted a libtool developer, and he responded as follows:

"Your configure script adds spaces after -I and -L before the directory.
GCC is ok with this, libtool not so much."

I patched OProfile's configure.in to remove the spaces and successfully
tested it.  I will commit this fix.
