[Buildroot] [PATCH/next v3 1/5] package/ti-sgx-libgbm: new package

[unixmania at gmail.com <unixmania@gmail.com>]

From: Lothar Felten <lothar.felten@gmail.com>

A custom ti version of libgbm for SGX graphics accelerator, required by
the binary libraries of the ti-sgx-um package.

---
Changes v1->v2
- Fix SDK version (comment in ti-sgx-libgbm.mk)
- Remove duplicate package in package/ti-sgx/ti-sgx-libgbm
Changes v2->v3
- Add DEVELOPERS entry
- Re-generate patch to include sys/sysmacros.h using git format-patch
- Fix indentation and remove stray empty lines
- Extract license from gbm.h header instead of distributing the whole
  file. This is safe because if the terms change in the header the
  sha256 hash will stop matching.
- Use HTTP to clone the Git repository (works with an HTTP proxy, which
  is better when building behind a firewall that blocks the git port).
- Use AUTORECONF=YES instead of the running autogen.sh script.
- Use INSTALL_{STAGING,TARGET}_OPTS instead of custom install commands.
- Add home page to Config.in
