glibc patch: version-gate _DYNAMIC_STACK_SIZE_SOURCE
This is a patch to glibc features.h which makes
_DYNAMIC_STACK_SIZE_SOURCE undefined unless the version is >= 2.34.
This feature was introduced with glibc 2.34 and without this patch, code
built against these headers but then run on an older glibc will end up
making a call to sysconf() that returns -1 for the value of SIGSTKSZ
and MINSIGSTKSZ.1 files changed, 5 insertions(+), 0 deletions(-)
