Subject: cross.bbclass: Remove usage of host flags for cross-compilation
X-Git-Tag: 2017-10~22
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=4b936cde58ca0a6f34092ce82640a02859110411;p=openembedded-core.git

cross.bbclass: Remove usage of host flags for cross-compilation

BUILD_* flags can't be used as TARGET_* flags even for "cross" packages.

gcc-cross buils leaks config.log's through "gcc-stashed-builddir" and
TARGET_* flags to libgcc cross-build through "gcc/libgcc.mvars" file
on "gcc-stashed-builddir". This means that if BUILD_CFLAGS contains
host-specific flags like "-isystem/usr/include" libgcc build will
fail "do_qa_configure" and "do_package_qa" checks.

Remove host-related flags from TARGET_* flags for gcc-cross build.
