Add a new patch to allow to build gcc 7.1 without extracting gcc/testsuite
directory.
This new gcc version require a kernel patch [1] to avoid a build issue with
____ilog2_NaN symbol. The following kernel version contain contain already
this patch :
4.11, 4.10.6, 4.9.18, 4.4.57, 3.18.50 and 3.12.73.
To build a toolchain based on gcc 7 and uClibc-ng 1.0.24, the patch [2] is
required to avoid a build issue due to missing aligned_alloc() definition.
