[RosBE] undefined reference to `__alloca' on newer GCC compilers

The distribution of the make tools bundled with RosBE is a little dated. As such, compilation of the code fails and RosBE doesn't bootstrap on host systems with a more recent GCC revision, i.e. at least with 7.x+ on Ubuntu 18.04.

The following diff does fix compilation.

{{ diff --git a/glob/glob.c b/glob/glob.c }}
{{    index f3911bc..8adbde3 100644 }}
{{    — a/glob/glob.c }}
{{    +++ b/glob/glob.c }}
{{    @@ -208,7 +208,7 @@ my_realloc (p, n) }}
{{     #endif /* _GNU_LIBRARY_ || _DJGPP_ */ }}

{{    -#if !defined _alloca && !defined __GNU_LIBRARY_ }}
{{    +#if !defined _alloca && defined __GNU_LIBRARY_ }}

{{     # ifdef _GNUC_ }}
{{     #  undef alloca }}
