[Buildroot] [PATCH v2 0/2] Add and workaround gcc bug 83143

[Giulio Benetti]

This patchset add gcc bug 83143 and work it around for package ruby with
a more specific CFLAG instead of the classic -O0. The work around has been
suggested here[1] and saves lot of memory since here ruby is the package
affected by this bug and it's pretty big.

V1->V2:
* fixed bug gcc version condition
* introduce this bug for BR2_sh and not only for BR2_sh4

Giulio Benetti (2):
  toolchain: introduce BR2_TOOLCHAIN_HAS_GCC_BUG_83143
  package/ruby: fix build failure due to gcc bug 83143
