Linking error in headless(--without-x) build

I can build libreoffice(latest code) completely without any error but when
I tried to build it in headless mode as mentioned here
https://wiki.documentfoundation.org/Development/HeadlessBuild

I am getting linking error for "headlessinst.o" as

usr/local/home/abhimanyusingh/Documents/libreoffice_headless/core/workdir/CxxObject/vcl/headless/headlessinst.o:
In function `HeadlessSalInstance::~HeadlessSalInstance()':
headlessinst.cxx:(.text+0x4f): undefined reference to
`SvpSalInstance::~SvpSalInstance()'


What I found surprising that in directory "workdir/CxxObject/vcl/headless/"
only "headlessinst.o" file is there. There is no file as "svpinst.o" for
"svpinst.cxx" which contains definition of "SvpSalInstance".


FYI for full build(without headless option) directory
"workdir/CxxObject/vcl/headless/" contains "svpinst.o" . It is having issue
only in --without-x build.


Any help on this would be really great.

Thanks
