Add 'glibc-compat-symbols.h' to force usage of minimal GLIBC symbols currently for memcpy only, used in our x86_32 and default gcc toolchain cmake file.
Note: JogAmp's minimum GLIBC is 2.4 due to '__stack_chk_fail' (stack overflow checking)
GLIBC 2.4 - March 2006 - Standard for LSB 4.0, Used in SLES 10
We could add compile/link option '-fno-stack-protector', however stack protection seems reasonable
and a pre 2006 distribution a bit too 'far fetched' for our multimedia bindings anyway.
+++
Added convenient script 'make/scripts/check-glibc-version.sh' to sort and list GLIBC versions per symbol.
+++
Besides openal-soft (commit 554b34927cd6a2e0c0ce227108ebf8521bcba889),
jogamp modules do not reference any GLIBC symbols > 2.4 per default!
If so, 'glibc-compat-symbols.h' should be included per default!
