Comment 9 for bug 343602

Trick to see hwcaps from /proc/self/auxv as seen by ld.so/glibc:
% LD_SHOW_AUXV="" cat </dev/null
AT_HWCAP: swp half thumb fast-mult vfp edsp
AT_PAGESZ: 4096
AT_CLKTCK: 100
AT_PHDR: 0x8034
AT_PHENT: 32
AT_PHNUM: 9
AT_BASE: 0x40000000
AT_FLAGS: 0x0
AT_ENTRY: 0x8ba8
AT_UID: 1000
AT_EUID: 1000
AT_GID: 1000
AT_EGID: 1000
AT_SECURE: 0
AT_EXECFN: /bin/cat
AT_PLATFORM: v7l

Trick to force hwcaps on a platform:
% sudo LD_HWCAP_MASK=0x0 ldconfig
now ld.so wont find any additional hwcap selected libs in the ldconfig cache:
% ldconfig -p | grep vfp
% ldd /bin/ls | grep vfp
