Re: [PATCH] Add --with-build-config=bootstrap-asan support

Please try this:

I just did locally "git log -2 -p|patch -p1 -R" - and wait until you sort that out with the patch reviewers, which seemingly didn't like that patch.

BTW: I am not sure whether it is possible with the current build system, but I'd prefer: if libsanitizer is not needed (i.e. no bootstrap-asan is used), it is only build as target library in stage2/stage3 and not also in stage1 as host library.

I think that patch has broken bootstrap for me. If I do a normal bootstrap, Stage1 fails with:

I should have quoted more. Note that the "g++" or similar is missing before "-D_GNU_SOURCE":

/bin/sh ../libtool --tag=CXX --mode=compile -D_GNU_SOURCE -D_DEBUG -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -I. -I../../../../libsanitizer/interception -I ../../../../libsanitizer/include -Wall -W -Wno-unused-parameter -Wwrite-strings -pedantic -Wno-long-long -fPIC -fno-builtin -fno-exceptions -fomit-frame-pointer -funwind-tables -fvisibility=hidden -Wno-variadic-macros -Wno-c99-extensions -g -O2 -D_GNU_SOURCE -MT interception_mac.lo -MD -MP -MF .deps/interception_mac.Tpo -c -o interception_mac.lo ../../../../libsanitizer/interception/

Thus, for libsanitizer, the $(CXX) variable is not set, when invoked via build root's Makefile. Which gets set via 'CXX=$$(RAW_CXX_FOR_TARGET)'
