gcc: gcc 4.9.x disable libsanitize

gcc 4.9.x enables building of libsanitize

- libsanitize needs some headers that are not available
in uclibc (netrom/netrom.h)

according to buildroot project:
- build fail with musl
- need wordexp with uclibc which increases uclibc size

[toolchain] invoke patch-specs.sh in the gcc/final install stage.
Patch up OpenWrts own cross toolchains to always search headers
and libraries in $STAGING_DIR, this should solve most issues with
missing headers, indirect linking and not found libraries.
At a later stage, all -I and -L flags will be purged from
TARGET_LDFLAGS and TARGET_CPPFLAGS.
