John Keeping 408bc354a9 toolchain/toolchain-wrapper: let recent GCC handle SOURCE_DATE_EPOCH ... When using precompiled headers, changing any macros defined on the command line will invalidate the precompiled header. With toolchain-wrapper adding __DATE__ and __TIME__, any commits to Buildroot will invalidate incremental builds regardless of whether the precompiled header actually uses those values (affecting _OVERRIDE_SRCDIR). GCC-7 and later support SOURCE_DATE_EPOCH and use it to define __DATE__ and __TIME__ internally, avoiding any impact on precompiled headers. Disable the custom handling in toolchain-wrapper if GCC is version 7 or newer.
