Commit 8b0aeafce2a22913e6a44818227f6a39e3225157 set 7 new variables in
g-ir-scanner.in:
export CPP="${CPP:-${HOST_DIR}/bin/@BASENAME_TARGET_CPP@}"
export CC="${CC:-${HOST_DIR}/bin/@BASENAME_TARGET_CC@}"
export CXX="${CXX:-${HOST_DIR}/bin/@BASENAME_TARGET_CXX@}"
CPPFLAGS="${CPPFLAGS:- at TARGET_CPPFLAGS@}"
CFLAGS="${CFLAGS:- at TARGET_CFLAGS@}"
CXXFLAGS="${CXXFLAGS:- at TARGET_CXXFLAGS@}"
LDFLAGS="${LDFLAGS:- at TARGET_LDFLAGS@}"
However, defaulting to CPP, CC, or CXX breaks some packages because they may
hard code CC to the system CC.
One such package is libostree which has the line
"INTROSPECTION_SCANNER_ENV = CC=gcc" in the Makefile.
Because g-ir-scanner defaults CC to a predefined CC instead of explicitly
overwriting it, the CC passed from the makefile is used, and linking errors
occur as a result.
Remove the defaults for the following and explicitly set the paths to the
proper cross-toolchain binaries:
CPP, CC, CXX
