By googling found this patch need to be applied http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/recipes-devtools/m4?h=thud&id=95ca077ab871ceff46c2052f324f879a1d624ff4 Can someone please help to figure out this issue and apply this patch in yocto.

You can apply the patch with git like here.

Or you can download the m4-1.4.18-glibc-change-work-around.patch and place it in a files subfolder in meta/recipes-devtools/m4/files and add add the following line to SRC_URI:

SRC_URI = "${GNU_MIRROR}/m4/m4-${PV}.tar.gz \
        file://ac_config_links.patch \
        file://remove-gets.patch \
        file://m4-1.4.18-glibc-change-work-around.patch \
        "    

file://m4-1.4.18-glibc-change-work-around.patch in SRC_URI will apply the patch for you.

You can also look for the location of remove-gets.patchand place this patch in the same folder.
