Emacs master build failing on RHEL 6.8 [image.c]

[Kaushal Modi]

Hello,

A recent change to image.c broke the emacs master build on my RHEL 6.8 system.

I get this error:

make[2]: Leaving directory '/home/kmodi/downloads/git/emacs/admin/unidata'
  CCLD     temacs
/usr/bin/ld: warning: libgmp.so.3, needed by /cad/adi/apps/gnu/linux/x86_64/6/lib/libhogweed.so.2, may conflict with libgmp.so.10
image.o: In function `gif_load':
image.c:(.text+0xa76b): undefined reference to `GifErrorString'
image.c:(.text+0xa7d8): undefined reference to `GifErrorString'
image.c:(.text+0xaefe): undefined reference to `GifErrorString'
collect2: error: ld returned 1 exit status

My librsvg version is 2.26.0 (Reference to a recent discussion around this topic: https://lists.gnu.org/r/emacs-devel/2019-05/msg00145.html).

My last emacs devel build was 5 days back using https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=cc71a82fc705a73fa3ef6cda3ec6bee1cb654d7e, and that works fine.
