pic_cxxflags.patch

Allow passing of PIC_CXXFLAGS to the configure script of libstdc++.
|
|
Without this change, libsupc++ would be compiled w/o PICFLAGS, resulting
|
|
in text relocations. Because for base tool chains, no 'dynamic_linker'
|
|
is defined (see 'libtool.m4'), 'dynamic_linker' is set to 'no', which
|
|
results in 'can_build_shared = no', which, in turn , results
|
|
in 'enable_shared = no', which, in turn, sets 'PIC_CXXFLAGS' to
|
|
nothing rather then '-prefer-pic'.
