Work around Sun CPP

Sun Studio CPP seems to insert whitespace in a different way than GCC's CPP.
GCC generates in src/fcobjshash.gperf:
[...]
"family", FC_FAMILY_OBJECT
"familylang", FC_FAMILYLANG_OBJECT
[...]
Sun Studio generates:
[...]
"family" , FC_FAMILY_OBJECT
"familylang" , FC_FAMILYLANG_OBJECT
[...]
leading to:
[...]
Making all in src
gmake[2]: Entering directory `/home/rs/src/fontconfig-git/fontconfig/src'
GEN fcobjshash.gperf
GEN fcobjshash.h
Key link: " " = " ", with key set "".
1 input keys have identical hash values,
use option -D.
gmake[2]: *** [fcobjshash.h] Error 1
gmake[2]: Leaving directory `/home/rs/src/fontconfig-git/fontconfig/src'
gmake[1]: *** [all-recursive] Error 1
gmake[1]: Leaving directory `/home/rs/src/fontconfig-git/fontconfig'
gmake: *** [all] Error 2
...maybe we could tuck in an additional sed to remove the whitespace, like:
[...]
fcobjshash.gperf: fcobjshash.gperf.h fcobjs.h
$(AM_V_GEN) $(CPP) -I$(top_srcdir) $< | \
$(SED) 's/^\s*//;s/\s*,\s*/,/;' | \
$(GREP) '^[^#]' | \
$(AWK) '/CUT_OUT_BEGIN/,/CUT_OUT_END/ { next; }; { print; };' \
> $@.tmp && \
mv -f $@.tmp $@
[...]
though I'm not sure what kind of guarantee CPP can give us/what easier option I might have missed...
