# GCC build: patch libgomp.so.1 (OpenMP runtime library) to replace raw SYSCALL instruction with
# function call into Graphene. GCC is not built by default with Graphene; use `make -C LibOS gcc`
# to build it. The resulting libgomp.so.1 is symlinked under $RUNTIME_DIR. This patched version
# makes sense only on x86_64 platforms. NOTE: We'd prefer to build libgomp.so.1 alone but it is
# impossible (the only way to build it is as part of the complete GCC build).
#
# We explicitly unset CC, CXX, AS environment variables for the case we're compiling the rest of the
# project with clang. This is because in GCC build, "defining certain environment variables such as
# CC can interfere with the functioning of make" (https://gcc.gnu.org/install/build.html). Indeed,
# defining CC=gcc or CC=clang leads to errors during GCC build.
