New description:

 I'm trying to bootstrap ghc compiler with downloaded ghc binary
 distribution (6.10.4). Passing some variables to ./configure for example:
 {{{
 ./configure LDFLAGS="-Wl,--as-needed -Wl,-z,relro -Wl,-z,combreloc"
 CFLAGS="-O2 -fno-strict-aliasing -fwrapv -march=i686" ...
 }}}
 results in running configure scripts in libraries with incorrect options:

 (for base library)
 {{{
 configure --with-
 compiler=/home/users/atler/rpm/BUILD/ghc-6.10.4/ghc/stage1-inplace/ghc
 --with-hc-pkg=/home/users/atler/rpm/BUILD/ghc-6.10.4/utils/ghc-pkg
 /install-inplace/bin/ghc-pkg --prefix=/NONEXISTENT --bindir=/NONEXISTENT
 --libdir=/NONEXISTENT --libexecdir=/NONEXISTENT --datadir=/NONEXISTENT
 LDFLAGS=-Wl,--as-needed -Wl,-z,relro -Wl,-z,combreloc  --configure-option=
 CFLAGS=-O2 -fno-strict-aliasing -fwrapv -march=i686 ...
 }}}
 Notice that --configure-option (added in mk/cabal-flags.mk) was not
 stripped for CFLAGS, actually it's stripped only for the first variable.
 This further results in passing --configure-option to gcc when testing gcc
 usability which obviously fails. Another interesting part is though
 compilation of base fails, compilation process still continues and ends
 with some mysterious error about not met dependecies.
