[SRU][focal/linux-riscv-5.8][PATCH 1/1] UBUNTU: [Packaging] Use gcc-10 for riscv-5.8 kernel configs

[Kleber Sacilotto de Souza]

BugLink: https://bugs.launchpad.net/bugs/1933856

With "UBUNTU: [Packaging] Use gcc-10 for riscv 5.8 kernel build", gcc-10
is used instead of the default gcc version in Focal for the kernel
builds. The same compiler version is also needed to generate the kernel
configs. Pass the "gcc" variable value set in debian/rules down to
debian/scripts/misc/kernelconfig so the same string is used.
