package/gcc: glibc >= 2.27 needs gcc >= 5 on aarch64
With the following defconfig:
BR2_aarch64=y
BR2_BINUTILS_VERSION_2_28_X=y
BR2_GCC_VERSION_4_9_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
The build fail with this error:
In file included from ../sysdeps/ieee754/flt-32/math_config.h:23:0,
from ../sysdeps/ieee754/flt-32/e_expf.c:29:
../sysdeps/aarch64/fpu/math_private.h: In function 'roundtoint':
../sysdeps/aarch64/fpu/math_private.h:311:3: error: implicit declaration of function 'vrndn_f64' [-Werror=implicit-function-declaration]
return vget_lane_f64 (vrndn_f64 (vld1_f64 (&x)), 0);
^
cc1: all warnings being treated as errors
vrndn_f64 function has been introduced in glibc code since version 2.27 [1].
So we can't build a glibc based toolchain with gcc 4.9 anymore.
Add a new dependency in the toolchain infra to avoid selecting
glibc toolchain using gcc 4.9.
