Bug#870176: libdrm: Make source package bootstrappable

[Daniel Schepler <dschepler@gmail.com>]

Source: libdrm
Version: 2.4.82-1
Severity: wishlist

Currently, libdrm is involved in build dependency cycles such as:

libdrm Build-Depends on valgrind
valgrind Build-Depends on gdb
gdb Build-Depends on texlive-base
texlive-base Depends on texlive-binaries
texlive-bin Build-Depends on libgd-dev
libgd2 Build-Depends on libtiff-dev
tiff Build-Depends on freeglut3-dev
freeglut Build-Depends on libgl1-mesa-dev
mesa Build-Depends on libdrm-dev

As far as I can tell, it should be sufficient just to annotate the
Build-Depends with "valgrind <!nocheck>".
