gettext compile fails in crosstool-ng build on cygwin

I am new to crosscompiling and I followed the steps from using-crosstool-ng-and-cygwin by MAKSYM SHYTE

The crosstool fails to build gettext when generating crosscompiler for i686-nptl-linux-gnu target

build = x86_64-unknown-cygwin
host = x86_64-unknown-cygwin
target = i686-nptl-linux-gnu or x86_64-unknown-linux-gnu


NOTE: This gnulib patch from Ken Brown is needed to get gettext module compile. Alternatively, it also compiles if we just comment out #include in /usr/include/sys/types.h as per thorrr from bountysource

[UPDATE1] building gettext module for host gives the exact same errors for the x86_64-unknown-linux-gnu target also.

The ct-ng build fails in the linking phase while building gettext module for host.

[UPDATE2] filled in all the logs before "collect2: error: ld returned 1 exit status"

1) The build logs show that the "building and installing gettext module for build" succeeding but it failing when "building and installing gettext module for host" - What could be the difference since build and host architecture is the same - x86/cygwin ?? Am I missing any configuration settings?

2) If anyone got the crosstool-ng working on recent cygwin releases for a linux 64/32bit targets, please share detailed steps or links.

[UPDATE3]

As I was going no where trying to crosscompile for linux(ubuntu) I tried arm-unknown-linux-gnueabi and armv7-rpi2-linux-gnueabihf targets, cygwin can generate the cross-compoilers just fine for both targets. Its strange that crosscompiler generation for 32 and 64 bit plain linux target fails in Cygwin. I am probably missing something trivial.

[/UPDATE3]

Anyone with recent success on (x86/i686)_linux target please share your steps or links.

Answer

The undefined symbols (XML_GetFeatureList XML_GetCurrentLineNumber XML_GetCurrentColumnNumber XML_ParserCreate XML_SetElementHandler XML_Parse XML_ParserFree XML_GetErrorCode XML_ErrorString) were defined in expat-2.1.0.tar - a separate package. I could not get that to link into the crosstool builds but I got past the gettext linker error by removing the following from the .config file

CT_EXPAT=y 
CT_EXPAT_NEEDED=y 
CT_EXPAT_VERSION="2.1.0"
CT_EXPAT_V_2_1_0=y
